Hi,
Reporting issues via app will help to attract attention for the product team and be helpful for them to work on the issue with enough details, thus it will take some time for the team to work it out.
Moreover, please try the beta version which "Addressed some reliability issues identified through crash reporting." which has some new testing features before the official released one.

Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
