~$ telegram-desktop

In fact, I had many probles with snap packages like with gnome-calculator or gnome-system-monitor. This applications was delivered as snap packages after normal install. But I don't think that this applications need to be as snap. After uninstall and install as normal app works correct.
But Telegram I cannot install as normal application via sudo apt install
because it is not in stadard ppa repository :( Only I can download AppImage from official Telegram website. But then snap is just a crap of ... (you know) and I recommend migrate to Flatpak.
Please, can you help where can be a problem with snap package of this application?
My Snap applications:
$ ls -la /snap/

vlc works correctly yet :) Thanks for any advice
PS: I tried refresh snap package via snap refresh
but it doesn't helps
sudo snap refresh telegram-desktop
snap "telegram-desktop" has no updates available
Thanks for reply
This problem affects me too. The first time I connected required snap interfaces to telegram, and it worked. But today the problem showed up itself again. I fix it by remove and install again telegram with:
Note that by now exists a telegram-desktop package within default ppa and you can install it by
Frist remove the packge.
Install it back.
Now perform another install using the default package manager.
