edu.mit.appinventor.aicompanion3: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent. Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.
It looks like you are using an old version of the extension, which is not SDK31 ready
where can i get the latest version for notification extension?
There are several notification extensions
Unfortunately you forgot to tell us, which one you are using
Generally you can find a link to all extensions in the extensions directory App Inventor Extensions | Pura Vida Apps
I'm using Notify_V3... unfortunately on the pura vida apps is also out of date extension that cannot be used for android 8.0 and above
An extension developer might stop providing updates at any time... in this case just use another notification extension, for example
Thank you so much
