We use universal links for an email link sign-in flow. In the last few days, we have received several reports of the links opening the browser instead of the app. Many other new users are able to sign-in with no problem.
Our AASA file has not changed and is hosted via an S3 website, which should have extremely high availability.
Anybody know what might cause this? How can I go about diagnosing it?
Thanks Jacob
I should have mentioned: I have gone through the debugging steps here: https://developer.apple.com/documentation/technotes/tn3155-debugging-universal-links, with the exception of sysdiagnose since we don't have a repro on a dev device.
Thanks for the post! My apologies for the delayed response. Could you provide the following information?
Are you currently implementing passkeys in your solution? If so, please take a look at this post that might be helpful: https://forums.developer.apple.com/forums/thread/756740?answerId=790908022#790908022
Could you link me to your AASA file? It looks like you already went over the Tech Note located at https://developer.apple.com/documentation/technotes/tn3155-debugging-universal-links. However, you didn’t provide the results of each step. Could you please post the links and results?
I’m looking forward to hearing back from you, particularly regarding passkeys, and seeing the links to the AASA files. Your patience is appreciated!
