Help/Support Game Center not working “Dawn of Zombies”

[Hexerii 2 iPhone 14 Pro Max 17.5.1]

iOS 17.5.1 - iPhone 14 Pro Max 

Dawn of Zombies: Survivor Game

Tried everything listed throughout the forums. Nothing has been successful to reinstate Game Center. Can install game from App Store and Game Center works and I have my previous data. 

Installed through App+, tried through web app, attempted sideloadly, uninstalled app+ and reinstalled twice. 
 

Thanks for any help. I see this has been an issue since February on some games. Just giving a heads up on another one…

I’m failing to see how this solves the issue at hand @KyosukeNanbu The link you shared specifically states there isn’t any issue when using app+, yet that’s what I’m using and Game Center still doesn’t function. Unless I’m missing something that information is useless ?

You mentioned you attempted sideloadly, what do you mean? Were you able to sideload the original version over the modded?

No, it wasn’t useless. It was giving you a list of options. You’re right, app+ isn’t working for you but did you try developer program + sideloadly or another option?

Nah it failed, I’ve attempted everything possible but not finding a work around, no plugins, with plug ins, app+, from App Store over modded, modded over App Store, web app, sideloadly installs, custom installs with correct bundle id… I know most of this doesn’t work but I tried anyway. I tried to access ifunbox and dig around the file system but I’ve been out of modding for years and ifunbox doesn’t work past iOS 8 🤦🏼‍♂️ Not sure if it’s a app+ issue or if Apple did something else in the newest update.

I don’t have access to a jailbreak on this version iOS, so that’s one option down. I’m not paying $100+ for a dev account when I don’t exploit vulnerabilities anymore I pay for app+ to avoid screwing around with memory/packet editing and DLL injections, and I’m old and work I don’t have time to reverse engineer a game I might play for a month if it stays interesting. So that’s two options down. Where I’m going with this is it’s a service that’s paid for and has been having issues since as far back as February that I’ve found and it still doesn’t work… I’m asking for a time frame or a possible idea of when or if the issue will be resolved. I appreciate you giving a link to options but the options listed aren’t working or aren’t feasible which does make them useless.
