Hi, I developed an iOS app which will do SMS filtering by following this documentation. https://developer.apple.com/documentation/identitylookup/sms-and-mms-message-filtering) I built the app and send Test Flights to different testers. All the Testers from Sri Lanka (an asian country) says filtering is working and they can see all the enabled categories on the Messages too (including iOS 26). But the testers from Mexico cannot see the categories and filtering is not working. On official documentation there is nothing about supported countries. But I found true caller article https://support.truecaller.com/support/solutions/articles/81000406341-how-do-i-enable-sms-filtering-on-iphone mentioning it support only few countries for SMS filtering. Currently available in the following countries: India, Nigeria, South Africa, Kenya, Bangladesh, Sri Lanka. Our previous Categories filtering are still available for: Australia, Bahrain, Canada, Ghana, Tanzania, United Kingdom, United Arab Emirates, United States of America, Zambia Following article https://clearstream.io/blog/ios-26-iphone-new-text-message-filtering is saying some categories are supported by only Brazil and India. Still I could not find any official documentations saying different country supports.

I have followed every step to make sure UnwantedCommunicationReportingExtension will work with my app. Let me list here Adding a new target UnwantedCommunicationReportingExtension to my project Adding API endpoint to Info.plist <dict> <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>ILClassificationExtensionNetworkReportDestination</key> <string>https://api.mycompany.net/call/v2/main/report</string> </dict> <key>NSExtensionMainStoryboard</key> <string>MainInterface</string> <key>NSExtensionPointIdentifier</key> <string>com.apple.identitylookup.classification-ui</string> </dict> </dict> </plist> Added classificationreport to Associate domain in Capability section. classificationreport:api.mycompany.net Created an apple-app-site-association file without json extension and returned this when api.mycompany.net called. I don't know whether to add app's bundle id or extension's bundle id. So added both. Complete apple-app-site-association below { "classificationreport": { "apps": [ "XXXXXX.com.company.appname.CallReport", "XXXXXX.com.company.appname" ] } } Checked the following website to ensure the file can be accessed. Both are displaying the file https://app-site-association.cdn-apple.com/a/v1/api.mycompany.net https://api.mycompany.net/.well-known/apple-app-site-association But I cannot call API https://api.mycompany.net/call/v2/main/report. It always fails with the following error Can anyone tell me what I'm missing? I tried for a week and was exhausted .
