I just went to the Expert Pro Roon Ready page. All I see there is a link to download the latest firmware and clicking on that took me to the Configurator page with the February 2019 firmware. Can you provide a link to the page referring to a November 2019 firmware?
I am unaware of any firmware update for the Expert Pro since 12/02/2019. We've got a separate thread on the Roon Ready problem that's had solid traffic since then including some this year. No one has mentioned an update since last February's update. The latest news we've had is from about 2 weeks ago when it was reported that Devialet were testing a fix for the Roon Ready bug and that a firmware update should be released soon.
What input on your Devialet are you using to connect to your Nucleus+, ethernet or wifi? The bug does not affect wifi connections. If you're using ethernet do you have a gigabit speed connection or a 100mbps connection? The bug affects gigabit speed connections and slowing the connection speed to 100 mbps is usually a reliable workaround for the bug.
The normal symptom of the bug is playback stopping for periods, often with the Roon app displaying an "An audio file is loading slowly" error message and the bug is more common when streaming high res files, especially 192/24, than with CD quality (44.1/16) files. What you're reporting is a separate issue which I have occasionally had. I would suggest turning everything off. that is powering down both the Nucleus+ and your250 and removing them from power. If both are connected to an ethernet switch I would also remove it from power. Wait a few minutes and power things up again but power the Nucleus+ and 250 up separately, one after the other. See whether that gets everything working correctly again.
The issue about the 250 showing as "Uncertified" is different. The Roon software checks a database on Roon's site for info and data about Roon Ready devices. The amp is telling Roon that it is Roon Ready but Roon doesn't appear to be checking the site, possibly because it has a regular timetable for checking it and it has a record of when it last checked and it is currently not due to do an automatic check. Lots of us had this problem last year when the Roon Ready update was released and there was a problem on Roon's site which was causing it then. Roon fixed it but the fix did not immediately take effect, we either had to restart our servers to restart Roon if I remember correctly or wait a couple of days when, apparently, the Roon application we were running would do its regular automatic check and details of our amp would appear. I had the same thing happen a couple of times recently and strangely the thing that seemed to fix it for me was rebooting my ethernet switch rather than my Nucleus+ or 140.
Lots of funny things seem to happen from time to time on a network. There's a tendency to think of them as being due to a bug, especially in a case like this when there's a know bug with the Devialet and Roon, and sometimes the cause is a bug but sometimes it's not. Rebooting everything often fixes the problem. Sometimes you need to reboot only one thing and that can work if you know which device to reboot but in your case I'd try rebooting everything. Remove power from all devices first and then power them up one at a time. Keep a note of the order in which you power them up. If it happens again, in a short period, repeat the process but power them up in a slightly different order, once again keeping notes of the order. If you have to do it a number of times you might identify an order which works better, especially when it comes to avoiding the "Uncertified Device" problem, but hopefully it won't come to that.
It's also worthwhile checking your network connections and Roon have a page on their Knowledge Base called something like "Best Networking Practice". Take a look at it because it has info about some common networking problems and also some issues associated with particular network devices such as some wifi routers and the like. You may find something in there which will help you stop the problem from recurring.
Good luck. A lot of us have had network issues from time to time and they can be frustrating. I've had my a couple of problems over the years and learnt at first hand how frustrating they can be, especially when they strike right when you're in the middle of playing an album which sounds great, you're lost in the music, and everything cuts out in the middle of a phrase and you have no idea what's going on.
