This is more an observation rather than a question and might help someone else.
I have a 4 disc set up using the original white discs. Occasionally, one of the discs (not always the same one) is not shown on the App but it is clearly working as other devices are connected to it.
Getting the ‘missing’ disc to show on the App simply requires that disc to be switched off and on.
Today I noticed another slant on this. When I opened the App it came up with no discs at all and was at the start of the full installation routine. I was just about to go through the whole process again when it dawned on me that I might be connected to one of those ‘missing’ discs.
Suspecting that I was connected to the disc nearest to me I powered it off and on and when I opened the App again everything was then showing.
I have the same problem, my app has gone back to the startup process. The discs are apparently working as I have good wifi coverage although I have switched off the blue light so can’t say that for certain. How do I get the app back to normal. I have four discs 3 are connected to the router via Ethernet and 1 is on Wi-Fi
