Getting lots of ANRs like this reported through Firebase Crashlytics:

Alright, created an issue at https://github.com/googlesamples/mlkit/issues/434. Thanks for the help, @argzdev.

Thanks for the extra details, @Thomas-Vos. Upon checking, even though mlkit is using Firebase components, the issue is not due to Firebase products but rather in mlkit itself. You could try creating an issue in https://github.com/googlesamples/mlkit/issues, they will be able to investigate this issue further. With that said, I’ll be closing this issue.
