Can confirm that this happens on mobile (installed via F-Droid on GrapheneOS). It will seemingly change countries or profiles mid day or overnight without a restart.

It is super annoying and causes sites I use to send me through all the verifications again / generate new tokens…

I have not witnessed this on Linux via flatpak but will keep an eye out…

Can confirm that this works - even better if they said no and then later ask you to send something “hey can you send so and so’s contact card” or. “Photos form the event”

And then you say “Yes, on Signal”

They will download right there
