Bug - iOS/Android - OnIsTranscriptionActiveChangedListener fires when users leave/join meeting during active Transcription

[ghost]

Describe the bug While a meeting is active and transcription is active, a user will leave the meeting (not the user who starts the Transcription) and the OnIsTranscriptionActiveChangedListener will fire and callTranscriptionFeature.isTranscriptionActive() will be false

To Reproduce Create a meeting with MS Teams Clients and Droid/iOS Calling client:

1. With all clients currently in meeting, MS Teams Client user starts recording transcription
2. Transcription active notification fires on all clients
3. User leaves meeting (not the user who started transcription)
4. On Droid/iOS Calling client: OnIsTranscriptionActiveChangedListener will fire and callTranscriptionFeature.isTranscriptionActive() will be false
5. Meeting continues and transcript is still active from the perspective of the MS Teams Clients and the meeting in progress

Expected behavior Either OnIsTranscriptionActiveChangedListener does not fire at all when a user leaves a meeting, or it fires twice with the last OnIsTranscriptionActiveChangedListener indicating that the transcript is still active.

Desktop :

• OS: MacOS
  • 1.4.00.29477
  • Client that started the transcription
• OS: Windows 11
  • Unknown Microsoft Teams version
  • Client leaving meeting

Smartphone :

• Device: moto G Power
  • OS: Android 11
  • com.azure.android:azure-communication-calling:1.2.1-beta.1
• Device: iPhone SE
  • OS: iOS 14.7
  • AzureCommunicationCalling', '2.0.1-beta.1'

Additional context This only happens when Transcript is Active. If meeting is being Recorded, the iOS/Droid clients do not experience the issue.
