What was the expected behaviour?

The tests should pass

Was it tested on latest Detox?

• I have tested this issue on the latest Detox release and it still reproduces.

Did your test throw out a timeout?

• I have followed the instructions under Identifying which synchronization mechanism causes us to wait too much.

Help us reproduce this issue!

No response

In what environment did this happen?

@rajathrao We use release build to run e2e test. Actually, we experienced the same issue as you, it happens randomly. I didn’t find a way to reproduce it.

weird, our release version seems to work on 19.1 but the debug version crashes

For additional context:

• Our Splash screen runs a number of Javascript promises in the background. We suspect that Detox might be losing synchronization with these initial JS promises
• Probably related to new Detox synchronization implementation?
• Issue occurs in any Detox version > 17.x
