Hi, everybody, so, I have this old app named Models in my ipad in which I bought a bunch of photo references for drawing, problem is, I updated ios to 15.3 and now it won't run, I searched for the developer to ask for help and they are nowhere to be found. Does a system downgrade would be an option? I just want tu run it once, screenshot the sh*t out of it and let it go. What do you think? Thx
