I see recent Sentry crash reports from 8.0.8 [1]:

https://sentry.prod.mozaws.net/operations/focus-android/releases/

But I see exactly 0 GV crash reports from GV 65 and 100+ crash reports from GV 64 (users who presumably should have been updated to Focus 8.0 with GV 65):

OTOH, my Focus 8.0.8 has GV 65, so either GV 65 is crash-free or there is a problem with our crash reporter.

Even though this is a Focus issue, I'm adding the [geckoview:fenix:m2] whiteboard tag because Fenix is relying on Focus to get beta testing of GV until we have more Fenix beta testers.

I tried 'about:crashparent' in Focus and got the following when trying to report the crash. Looks like a mismatch between a-c and GeckoView.

Dylan said he will fix this bug. He says the problem is the Focus 8.0 is using a version of A-C that is not API compatible with GV 65.

Nick says fat AARs (bug 1508976 and bug 1522581) will fix avoid dependency problems like this.

Dylan's new plan is to skip GV 65 and update Focus 8.0 to GV 67 Beta (bug 1531858). Assigning this bug to myself as a reminder to verify that GV 67's crash reporter is successfully submitting Focus crash reports to Socorro.

Deferring to [geckoview:fenix:m4] because Dylan is going on PTO for two weeks and Vesta says updating Focus can wait until April.

Yep! We're getting Socorro crash reports for GV 68 in Focus 8.0.9:
