I have my Instant App on Beta pre release but I am not able launch the Instant App through the app link. Instead it is taking me to the web browser. Any help?
I keep having the same issue myself. My solution has been to go to your Instant Apps settings and toggle Instant Apps off and back on again.
You should be able to get there via Settings -> Google -> Instant Apps
Similar problem as pre-release instant app cannot be launched through dynamic link
If you already tested with alpha or local, please check your distribution area as listed in that question.
