Iphone 8 keep crashing

Hey i been playing this since the start of HS and i’m a HUGE fan.
Exept there are so many crashes. I been in the app store to check req and it fits the bill for recomented.
My guess is the ram there is the problem.
Note.
In Mercenary mode there is a crash epedemic. When it launched it worked fine but with every patch it keeps getting wors.

It reach a point where the game is unplayable and not fun at all now.
Could you maby consider making a Lite vertion or comprimise the game like.

It’s a card game and is the most heavy req proformance i seen in any APP

With live and hugs for the Hearthstone team realy love it and i play it mostle when i am on the move.
