local push notifications depends on Persistent Connection, if you are on the google play store version of the app you may want to ensure the setting is set to Never.
Settings > Companion App > Persistent Connection
If you need the connection then please check the logs I mentioned earlier.
Settings > Companion App > Show and share logs
it will show a failure for why the persistent connection could not be made. If no failure is shown then force stop the app and open it again to see if there is an error. Again this is IF you have Persistent Connection set to anything other than “Never”. If you are on the minimal version of the app then you do want it set to “always” so you can get notifications. In that case you will see an error in the logs if the app could not establish the connection.
