Hm, that doesn't look like a crash though? It's just a lock being in waiting state. What's the crash messsage?

[short-dsb]

Good morning! 🙂 This is an ANR, not a crash. We had been on v2 until recently and didn’t start seeing this issue on our dashboard until after upgrading to v4.

At the moment, it’s our third most reported issue and on the verge of exceeding our bad behavior threshold, which will negatively impact our app’s discoverability.

Any help you can provide would be appreciated.

[mrousavy]

Ah okay - well I currently have a lot of other things to work on, if you want to prioritize that issue consider sponsoring me through your company :)

[short-dsb]

We did! 🙂 Although our priority is the RN 0.74 upgrade, it would be nice to uncover the root cause of this issue as well.

Thanks for all your work.

[mrousavy]

Ah sorry with which company?

Although our priority is the RN 0.74 upgrade

Yep, that's high prio for me as well - just lots of effort

[short-dsb]

Ah sorry with which company?

Sent you an email. 🙂
