Honestly, not much to say.
Tried with the main switch (brave’s extensions) on and off.
Perfectly fine in chrome.
Annoying but not serious/critical.
I posted screenshot in another place in forum but there is not much to see per say.
Brave 1.0.35 (current version from play store)
Two more things
apparently it does not affect all gifs
to the majority that do play, my phone knows there is no audio since volume buttons are affecting ring, not music, volume. That clue might help fixing this quickly.
