Upkeep stop failing to trigger
I recently played a game where I had the enchantment Virtue of Persistence in play, and a Takenuma, Abandoned Mire in hand. During my opponent's turn, I set an upkeep stop on my own upkeep, with the plan of channeling Takenuma in response to my Virtue of Persistance trigger. The game ignored my upkeep stop and forcibly resolved my Virtue trigger without giving me priority to channel Takenuma in response. The stop worked after the trigger, holding my priority until my first main phase, but I should have had the opportunity to respond to my Virtue trigger. Honestly this shouldn't even require a stop, as its a trigger that goes on the stack and requires my opponent to then pass back. Please get this right, the upkeep stop seems extremely inconsistent in how it interacts with on board triggered abilities.
