Thanks so much for responding! Do I just make my own Signature using xcode or whatever and send it over to ESign on my device or is there another way? This is my first time doing something like this so I'm not very familiar. If there's a link with all the steps please please send it to me!
I've been trying to use ESign but I can't get the mobileprovisions for the app to work and I keep getting an unverified or unlaunchable app so I'm not sure what to do at all. Is there a chance I could try to extract the official ODR asset files (since I'm assuming that's how the maps are downloaded) from the original app and try to merge it with your ipa so it finds the files already there and doesn't have to download it?
