I'm talking to an affected user in 266560-h. @bummytime: Do you know what the cause of this crash is or if there's a workaround that could help the user for now? Also, is there any information from the user you'd find useful?

[bummytime]

@SiobhyB Unfortunately I was not able to repro this issue even a single time — and I tried a LOT. TBH, this screen is probably overdue for a refactor.

As far as this customer is concerned, logs with Extra Debug turned on are always helpful. :-)

@bummytime: Thank you! The user's updated the ticket with the logs. Let me know if there's any other useful information from them we can provide.

[SiobhyB]

Another affected user in 269362-h. They mentioned that the app keeps crashing for them when they attempt to open it.

[SiobhyB]

This came up again in 271014-h. The user has tried uninstalling then reinstalling the app multiple times.

I've verified that this crash is no longer present after releasing 9.6.1 to all users, good job with the fix @etoledom 👏
