I want to thank you guys for keeping me motivated and to keep trying. GOOD NEWS! I now have the app working on my 15 pro on ios 17.4! Backstory. When you get a new iphone and an app you had on your old phone isn't available in the app store anymore, you're screwed.... So I thought... I found the original IPA file for the program and first tried to email it to myself. Gmail won't allow you attach an .ipa file! So crazy. They must have some deal with apple here, but I've never seen something like this happen. I tried to even rename the file as .jpg and gmail still won't let you email it as an attachment. I did save it on a memory card just to have a backup. The version of the app from my old backup was an older version of the app than on my new phone that had the cloud icon next to it, (1.91, vs 1.94) and I first tried to copy the old file onto the new phone (since the app on the new phone had the cloud icon on it, that means it tries to DL the app from apple, but it can't since the app is no longer on the app store) After dragging the older ipa version of the app onto the new phone with imazing, I could see both listed, 1.91 and 1.94. When I tried to click "install" for the older file with Imazing, I kept getting this error "the code signature version is no longer supported" Yea, I was pissed when I saw this! I don't know what that means.
Next for the hell of it, I clicked on the 1.94 version (remember it shows this because it's on the home screen on the new phone, but has that cloud icon next it). I right clicked and hit "install" and instantly the cloud goes away! I'm thinking, hmm, how the heck what this so easy? and no way it's going to work when I click it. I click the app on the phone and it opens!!!! It's working! I don't know how or why but this fixed it. After many days and nights trying everything and posting about this everywhere, contacting the app developer, etc. Imazing fixed it!
