[BUG] COMM activity tab broken on 2.48.2

Summary of issue: Opening COMM doesn't load the latest activities. You need to evoke multiple refreshs for it to display normally, and even then sometimes it's stuck in an endless loading loop.

Device: Pixel 2 XL

OS: Android 10

App Version: 2.48.2

Additional information: I noticed that the 4-tap debug log is throwing an error when opening COMM, see the output below.

[FMOD] Please add an 'FMOD Studio Listener' component to your a camera in the scene for correct 3D positioning of sounds.
