Ran into this issue w/ my team once we implemented a SharedExtension for our main app. As stated above, everything seemed to check out when we would verify permissions/entitlements via Xcode and the dev portal. Our solution was to add any missing provisioning profiles to the ExportOptions.plist (in our case the missing prov profile we added to the SharedExtensionApp) as stated in our build error: Error Domain=IDEProvisioningErrorDomain Code=9 ""SharedApp.appex" requires a provisioning profile with the App Groups feature." UserInfo={IDEDistributionIssueSeverity=3, NSLocalizedDescription="SharedApp.appex" requires a provisioning profile with the App Groups feature., NSLocalizedRecoverySuggestion=Add a profile to the "provisioningProfiles" dictionary in your Export Options property list.}

I am currently experiencing the same issue described above. When the URL endpoint is a PDF document the share option is not available for my app in the share menu. All of the NSExtensionActivationRule(s) are thrown in our plist to no avail. I will be implementing this on the Android side tomorrow to help make sense of this. Please consider the issue alive and well...

Looks like this is broken behavior coming from Safari. As of today, I cannot share anything from Safari (my app will not show up in share context menu). Sharing from Chrome shows ZERO issues... It's Safari.... I'm also seeing inconsistent behavior sharing from Adobe to my app. The share is only successful 1/10 times or so, if you're lucky. In the share extension everything behaves per other use cases, and I store a path to the file (stored in shared app container) in user defaults. In the main AppDelegate, the userDefaults value only pulls non null 1/10 times. If I step through the share extension app, the userDefaults value is populated EVERY TIME in a debug session.. Zero issues on Android...

Safari is the issue, try sharing from a Chrome browser on an iOS device..

I had everything working on iOS 14.7. Just updated to 15.0 and BOOM broken. Works 1/30 times or so.
