Unable to launch Android app with Synced Realm instance when offline

MongoDB Atlas App Services & Realm Atlas Device Sync
,

We recently integrated Synced Realm with our Android application. While its working fine both online and offline. However, after about 30 minutes of inactivity, the application gets stuck on launch even though we’re using Realm.getInstanceAsync.

We’re using Synced Realm with JWT auth.

Please find attached the code (have removed some internal constructs, so please ignore the IDE warnings) along with the output of debug logs. Kindly let us know if any additional information is required.

@Sarthak_Garg : Welcome to the community.

Can you please enable realm log and share the result with us, I suspect you are facing an already reported issue.
