While I don't own these pumps, I do have a note 20 and got the android 11 update the other day. I too have noticed some things that have an app to control are little wonky since the update.I've had a lot of weird things going on with all my phone required devices since my phone upgraded to Android 11. I've managed to find weird ways around it all, but it is annoying. I noticed someone else mentioned having a pixel in here as well and I'm wondering if the early Android bump for us is relevant to everything bugging out.
