I don’t have any idea where to flush the cache
![:frowning: :frowning:](https://community.home-assistant.io/images/emoji/twitter/frowning.png?v=9)
you can try clearing app cache
open settings on device (not in the app, close it)
apps/app management
scroll and find home assistant and select it
select storage/storage usage
select clear cache.
it maybe slightly different depending on android device
The notification has gone.
