Signal update or not update ? App as system app

/e/llo the community. I have a notification prompt to update signal in /e/ 0.2 shall I update it ? Or wait for next /e/ OS system update with TWRP ? Cause signal is a system app. And what is recommended for other apps like telegram and so on ? Thanks

Go ahead and update it, as for telegram the Fdroid repository will notify you of an update.

System apps should not be updated from external sources like F-Droid.
