iPhone smart battery case not charging if chin has pressure unapplied

I have an iPhone 7 smart battery case on my SE 2020 (was no option for the 7 case that is why it says 6s) and if any pressure is applied on the “chin” it stops charging. This is especially annoying because of you have it in your pocket and sit down it does not charge. It is cracked right at the sides above (where the bottom corner of the phone rests not the outside corner of the case) on both sides as is common on these but not I have glued it back together and it still does this. Any help would be appreciated.
