I’m using actionable notifications to remind me of putting the trash out. Since a few months I noticed that the notification no longer gets dismissed when clicking the action button. However, the action is received in HA (and processed by an automation), yet the notification does not disappear from my phone.
I’ve experienced this as well (albeit intermittently) for a while. I believe there is an open GitHub issue (couldn’t quickly find it) and is limited to situations where multiple notifications are sent rapid fire. My memory is it was an android issue related to it implementing a sort of ‘cool down’ when a single app sends multiple notifications. I also seem to remember a bandaid fix being to assign the notifications to groups.
Are you sending more than one notification roughly simultaneously?
The grouping fix definitely works if that’s the issue (I added it to my one set of notifications that all come in at once and have never had an issue with them since). I’d try it and see if it fixes your issue.
