lovefromisrael with 'aurora'.. why?
Suggest trying to install the standalone, self-updating APK directly from their site. You should give a battery optimization exception in order to have notifications use the websocket connection. Set the apps permission to allow for installing from unknown sources for the self auto-updating feature to be active.
Aurora store is a front end for the play store and is known to be problematic.
Note: advise that you uninstall the current signal app from aurora first, reboot the device, and try again with the official standalone apk.
EDIT: @lovefromisrael, No, there isn't. Thanks for catching the type.
is there really such a thing
