Enchanted Booster not activatable in HotM
For now you can get around the bug by activating the booster before you enter HoTM. They stack so you can use multiples to save going back an forth to LA. From your post it sounds like you already figured that out, but maybe this will help others.
Bumping this for great justice!
Seriously though, it’s annoying that you can’t time your uses of them until you get a match pop and instead have to sit out several minutes of your buff while waiting for one to show up.

I reported this as a bug yesterday too – the new xp booster is only 20 mins duration; popping two in LA before queuing gave me two matches with only a few minutes remaining. Assuming it’s a bug, and assuming the booster just has to be active before a match ends to get the bonus, I’d ideally be activating them towards the end of matches. Mind you a 20 min boost is a bit mean to start with…
