Help/Support Unable to sign/install AC Mirage using Apple Dev

[GameBooth 0 iPhone 15 Pro Max 18.5]

Hey gang,

I’m trying to install the Assassin’s Creed Mirage game from the site using the Apple Developer method (SideStore really doesn’t like the ipa for some reason, tried that) and keep getting an error. 
Something went wrong while signing this app. Please try again later. If the issue still persists, ask for support on iOSGods.com.

So,  here I am 😂 

When I fill out the form, I input my Apple ID, the app-specific password I’ve set up, my UDID that I’ve copied from my dev account (and triple-checked is accurate). I’ve tried with no Team ID and with my designated Team ID. I’ve tried leaving the Bundle ID blank, putting in a custom one and pasting in the default from the app page. 
I’ve tried doing it with and without my VPN, on Safari on my phone and on my Windows laptop. 
I’m running out of ideas and I refuse to pay again for the mobile version of a game that I bought on release on my Series X. I know there’s the Xbox Remote Play option but I figured using the app rather than that would be less battery intensive. 
I’ve definitely got VIP Pro here and a paid Apple dev account. 
I’ve got a feeling the solution will be staring me in the face but I’m the most beginner or beginners to developing 😂 

Sorry for the long post. Hopefully someone can help!

The apple dev program install has been broken for awhile now and @Rookstill has no plan on fixing it

If you have apple dev account I'd suggest you export the certificate or use Feather app to install. To get the IPA follow this guide https://iosgods.com/topic/93697-downloading-installing-apps-from-the-iosgods-app-using-sideloadly-on-your-pc/#comments

We have fixed it multiple times, but it keeps breaking..

So, short version is I’m scuppered and need to use the method that @Laxus has posted? Well, now I kinda wish I’d not wasted the £80 on the dev account 😂 

I will give that method a try after work, thanks!

A dev account is worth spending imo, you can also share or resell the certificate to 100 people and you can control the app entitlements yourself. Using apple dev program install and using certificate with Feather / Esign app to sign is the same anyway
