it is possible. I remember in the telegram if you installed on a different computer. It will show notification on all of them, it is related to the Cloud synchronization. But I am 100% sure. For your information.
I’ve been heard #matrix quiet often. Could I ask in the chat function, does it have this read function? I mean if someone sent you a message. After you read. It shows two check signs like that.
Thanks! i use signal; telegram more often. it's hard to register matrix.?
@Sphinx if you don't want to set up your own server, just go to https://element.io/get-started (previously riot.im, but they've rebranded) and create an account with the matrix.org server
Thank you for your information.
i just found there is typo "i'm not 100% sure"...
@Sphinx yes, it has message-seen-status (can be disabled by the user)
