True, why not just use Telegram? /s

Thanks for proving my point. Not the default, in a double nested menu, and with no warning what so ever about the security implications.

Other more actual security focussed apps prevent notifications showing the message content by default. This is afaik also possible in Signal, but not the default and buried deep in the settings somewhere. Signal has a long history of prioritizing convenience over actual security, despite all their rethoric suggesting otherwise.
