Good but somewhat frustrating

Some filters are kinda nice but why can’t I choose specific filter for a specific photo?
I purchased “the lab” thing even but I still have no clue how to change the filter.
?? It’s rather frustrating ??‍♀️??‍♀️ also watching a longer ad at once for”mission” would be nicer than clicking the screen every single second because sometimes the ads don’t even load... lastly filter pack in bundle with a bit of discount would be better option than buying one single film for 1.09$ .. it’s a bit expensive..
Despite my criticism, I definitely see potential for this app though..
