Can't Save notifications preferences at all.

[michalhojan]

Few people in my team including me have problem with notifications.
We can't change and save channels notifications setting at all. 
We tried change that on web and desktop app - nothing works.
it's look like we can't save that settings.

Any Help and Advice?
