@colorgold thanks for filing this. FirebaseUI 4.3.2 is almost a year old (released 03/26/2019) so we can no longer really accept bug reports from that version (especially if they are hard to replicate locally). The latest version is 6.2.0. Can you try upgrading your app to a later version of the library and see if you still experience this issue?

colorgold · 2020-02-12T20:57:02Z

6.2.0

I don't even know where I found the 4.3.2 version, but I also could not find the 6.2.0 version on the Firebase website. I have gone ahead and updated it. So far, the issue has not come up again. Thank you!

samtstern · 2020-02-12T22:50:35Z

@colorgold oops looks like we had an outdated docs page somewhere. We're gonna fix that ASAP.

samtstern · 2020-02-20T16:56:01Z

Looks like @wakim has this issue on 6.2.0 so reopening.

samtstern · 2020-03-25T17:49:06Z

The fix for this issue has been released in version 6.2.1

deltaguita · 2020-04-17T09:54:02Z

@samtstern
Still happen on 6.2.1

wakim · 2020-04-18T15:46:05Z

Still happening, but now my workaround is not working. I'll have to revert to the previous version.

The device that crashed was a Nexus 5X.

@wakim would you mind opening a new issue about this? Also are you able to reproduce it at all?
