Can’t log into Qobuz through Focal/Naim app

Tried to log in on my Muso 2 and my QB2 using my iPhone and iPad, but got login error messages in all cases. I can log in via the Qobuz app and cast to my Naim devices via Qobuz Direct.

Also, no problem logging into Qobuz on my Wiim streamer using the Wiim app.

Morning after edit - Looks like logging out from Qobuz on the Naim/Focal app and then logging back in will fix it.

What i have to do almost every other day. My naim app is on android.

Annoying.

What struck me as weird was that it happened simultaneously on my iPad and iPhone. This suggested a change in the app itself.

An Apple update?

It tends to point towards an app update (Qobuz or Naim) that has logged you out; it is as if they do it to see if you can remember your password.
