App42 blocks main thread after application becomes active

+1 vote

Hello!

The app is freezing every time it becomes active. It seems that it synchronizing the data on the main thread and locks it.
 
Sometimes during this process splash screen from our app is visible, but we have seen random screen from our app instead of splash and it also continues for ~10-20 seconds. (See video - https://www.dropbox.com/s/aque3itfprr25c2/IMG_0314.MOV?dl=0)
 
The worst case is when a user is prompted with any iOS permission (for example 'Camera permission') and after confirming he need to wait ~10-20 seconds before app will become responsible.  (See video - https://www.dropbox.com/s/zlff52u0h294uxg/MUSEUM_FREEZE.mov?dl=0)
 
For testing I've created a new project and have linked 3.5.5.3/AsyncAPI/Shephertz_App42_iOS_API.framework and I have the same issue.
 
Then I've tried to disable all tracking services, but it doesn't help:
 
    [App42API setOfflineStorage:NO];
    [App42API enableCrashEventHandler:NO];
    [App42API enableAppStateEventTracking:NO];
    [App42API enableAppAliveTracking:NO];
    [App42API enableEventService:NO];
    [App42API enableApp42Trace:NO];
 
All these issues are very critical for our application and UX and we hope that you can help us to improve the performance.
Thank you!

Any news with this bug?
I have changed that call from Sync to Async in the SDK. Now it will not block the main thread. Please download the modified SDK from here( https://www.dropbox.com/s/r1g4cqnnxy7etes/Shephertz_App42_iOS_API.framework.zip?dl=0 ).
Let me know if you have any queries.
Thanks, now it works as we wanted!
