SUMMARY
Group effect or effects applied to group, does not work properly on Flatpak version.

STEPS TO REPRODUCE
1. Add audio clip to timline.
2. Cut clip into three pieces / clips of similar length.
3. Select three pieces / clips.
4. Add volume effect to all three clips.
5. Enable Group Effect.
6. Click on one clips to activate it.
7. Add keyframe to volume effect.

OBSERVED RESULT
Keyframe is only added to active clip and not to other two parts. Occasionally, keyframe might be added to two clips, keyframe is sometimes set to "discreet" interpolation mode.

EXPECTED RESULT
Keyframe to be added to all 3 three clips.
