Santiago Andrigo, I’m unable to reproduce this using the 2.20 version of Mozilla VPN on Android 14.

I think that this was already addressed via https://mozilla-hub.atlassian.net/browse/VPN-4830 ( https://mozilla-hub.atlassian.net/browse/VPN-4830|smart-link )

Thanks Bianca Hidecuti. I just downloaded 2.20 and I can still reproduce. I do have an Android fork, so maybe it’s just this fork? (reducing to Medium) Do you have a Android 13 device around to try this with?

Santiago Andrigo, are you reproducing this while being on production or stage server?

After further investigation, I am also able to reproduce this on Mozilla VPN 2.20, on Android 13/14 - but only on production server. On stage the issue is not reproducible - attaching a video as well.

Santiago Andrigo , Bianca Hidecuti Yes, I can repro in production too. App hangs as soon as a I select the 'Sign Up” or “Already a subscriber” button.

Vinoo Cherian Is this something that we could tackle in the next sprint? Do you remember why it was taken out of Y Sprint?

Santiago Andrigo, given it’s super likely that we are moving out of in-app auth to custom tab, is this something we want to spend time on?

Agreed. Marking as Blocked and referencing the epic that Lesley is working on.

Verified using latest 2.23.0 (2.202405290156) build on Android 11/14, the issue is no longer reproducible. The user can sign in while the TalkBack is on. Marking this as fixed.
