Sometimes unable to activate abilities at instant speed
I don't know what specifically is triggering it, but I just had a game where my opponent boardwiped and I played Brought Back, targeting Dawnbringer Cleric. I had a Shadowspear on the field and 1 land available, the opponent had a Heliod. With Cleric's ETB on the stack I wanted to activate Shadowspear so that I could destroy said Heliod, but arena wouldn't let me. It wouldn't even let tap the land...
This is the most recent occurrence, but I have noted several other instances in play where I had possible responses based on on-board instant speed abilities and the game just blew right past me as if I didn't.

You need to be in full control to respond to your own spells/abilities. In this case, you also could have used the Shadowspear's ability before you brought back Dawnbringer Cleric.
