Layer suspension now works on mobile, let's give this a try once again.

android/app/src/main/java/org/jitsi/meet/MainActivity.java

             = new JitsiMeetConferenceOptions.Builder()
             .setServerURL(buildURL(defaultURL))
             .setFeatureFlag("welcomepage.enabled", true)
-            .setFeatureFlag("resolution", 360)
             .setFeatureFlag("server-url-change.enabled", !configurationByRestrictions)
             .build();
         JitsiMeet.setDefaultConferenceOptions(defaultOptions);

ios/app/src/AppDelegate.m

 
     jitsiMeet.defaultConferenceOptions = [JitsiMeetConferenceOptions fromBuilder:^(JitsiMeetConferenceOptionsBuilder *builder) {
         [builder setFeatureFlag:@"welcomepage.enabled" withBoolean:YES];
-        [builder setFeatureFlag:@"resolution" withValue:@(360)];
         [builder setFeatureFlag:@"ios.screensharing.enabled" withBoolean:YES];
         [builder setFeatureFlag:@"ios.recording.enabled" withBoolean:YES];
     }];
