Thank you for your reply!
Yes, unfortunately, see github talk-android issue 257
[My post gets rejected when I add the link here ;(]
I switched to the Matrix/Element (old Riot.im) solution hosted on my own
server and all works well. Of course, the push notification server is
not on my server but in Matrix’s.
Why of course? Doesn’t the matrix client only connect to the server you
There’s always someone in between to traverse the notifications being
WhatsApp, Signal, Telegram, Element, Talk, whatever.
The solution, for my point of view, would be p2p but there are few
options out there. The best I’ve tested is Jami but it has so many flaws
that couldn’t make it work properly. Still, it’s a work in progress and
I would keep following their development.
I do not see how p2p helps in push notifications. If anything, it makes
the development more complicated, as you cannot rely on any peer to keep
sending you notifications. This problem you do not have on (self-)hosted
solutions, as there you can assume that the server keeps sending you
notifications as long as you have a connection. (If the server is down,
the complete service is down anyway.)
Nevertheless, thank you for the hint, always good to have alternatives.
