I remember in the past the members had problems if their amps were in an alcove, I know I did, but the problem went away after firmware upgrades. My iPhone and iPad apps are stable and never give me problems, so maybe your problem @Dan is caused by the amps being in a cupboard. You don’t say whether your amps have the Core upgrade, and I don’t know if this will make any difference (perhaps one of our more knowledgeable members could chip in here), but make sure you have the aerials attached to each amp, have one pointing up and the other pointing horizontally. If the aerials are able to pick up the signal from the remote, it may be worth investing in one of those remote types that consist of a screw on connector, a length of wire and a 3-4 inch aerial with a flat base.
