[ChiY119]

When app is uploading to Apple Store, I got "error itms-90035"...
MozillaAppServices.framework/sdk_generator.sh is not preperly signed.

I got this error message.
Thanks

@ChiY119 Hello, is there a reason you are trying to upload the app to the app store? Have you forked the codebase into your own app?
