[iOS] Apptentive message sending getting failed after library upgrade from v5.3.4 to v6.0.3

[KarthikSugunan]

We have migrated Apptentive SDK from v5.3.4 to v6.0.3, and we are facing issue while sending messages through Message centre.

Issue is observed on upgrading the app with the older version of Apptentive SDK v5.3.4 to the new version of app with Apptentive SDK v6.0.3. When a messsage is sent using Message Center, its showing failed till we kill and relaunch the app after installing new version of app with Apptentive SDK v6.0.3.

Note :
Issue is not seen when we do a fresh install of application with Apptentive SDK v6.0.3.
PFA screenshot for reference. Thanks.

Can you please help us to resolve this issue?
Also, let us know if you need any other information.

Would you be able to supply verbose logs when sending a message? This will help us diagnose the problem. (Set ApptentiveLogger.logLevel to .debug early in the app lifecycle)
