Wow I had no idea you could actually “downgrade” things to be compatible with S1. (My units all came with the later app that force updated itself, but appear to be compatible with S1). They had given me the idea the device firmware was ratcheting forward, so once upgraded no way back.
Did this change during all the noise? (Entirely possible I was oblivious)
Because it is older it has problems with dark mode/light mode. But it is as fast and reliable as ever.
