Google Tag Manager causes video to stall

[BobAchgill]

On Android 8 playing consecutive 5 sec local videos using a JS playlist ... after a few videos the next qued video opens but either does not auto play (shows the play button) and must manually press play to proceed or after a few more videos dont auto play will just get stuck... with no play button.

Commenting out the GTM for the page resolves the hang problem.

It seems that GTM is trying to do its work of phoning home to Google while Reference Browser is trying to start the next video.

This issue does not happen on Firefox for the same playlist.

Is this a bug?

Is there a suggested work around for GTM settings when used with Reference Browser?

I can supply a test case if that's helpful.

Please reference the test case I emailed in last week to...

I have tried Nightly against the test case and it does a lot better now... it now plays 70 5 sec videos then hangs. So something is still not right. I think I notice that memory usage increases about half a MB with each each 5 sec video played. That begins to add up. What should I try next? Is this expected behavior? I have to do a Force stop on the app to clear the hang condition.
