New crash on 1.7.1 related to Telemetry (reports from Crashlytics)

[lluisgerard]

Describe the bug
The issue was clear with 1.7.0 because it happened right when you opened the app.
With version 1.7.1 it may not happen often but I receive reports from Crashlytics.

To Reproduce
I don't know how to reproduce, I get crashlytics reports.

Expected behavior
Not crash

Thank you for the report, I'm looking into the issue.

Thanks! Let me know if you need any more information. As of now I see 10 crashes affecting 5 users (according to Crashlytics reports).

@MichaelGHSeg Thanks for looking at this. As we get more people into our latest release we see more reported crashes that are highly concentrated to the same users. So far I could not see a specific trait that could help.

Do you think it could be possible to downgrade to version 1.6.2? could that cause any other issues? Thanks

[MichaelGHSeg]

There shouldn't be any issue with downgrading. There hopefully should be a fix out soon as well.

[MichaelGHSeg]

1.7.2 is out and should fix the issue. Thanks you for the help!

[lluisgerard]

@MichaelGHSeg Thanks! I will update asap 👍
