Playing on mobile using a Samsung Galaxy S9. During game one opponent executed an infinite loop using Cathar's Crusade and Scurry Oak. I had a wrath in hand so I waited for them to make their tokens. I tapped out all of my mana so I could pass turn without having to resolve their triggers. Opponent made about 80 tokens then passed their turn. I noticed that my timer had been running down during their turn even though I was never passed priority while they made tokens. My turn started, I drew a card and they won the match as if I had timed out. I unfortunately don't have a log file because this was mobile.
