Web console: Policy Loading... forever

Hey

I have an issue for some while  now in the web console. Most of the times when I log in, it will only show me "Loading..." in the column policy. This happens in Edge Chromium as well as in Firefox.

Right now I had a look at the properties of a client and suddenly the line where I can choose the policy was gone and the message told me, that the client wasn't assigned to our account anymore.

What also happens sometimes is, that for some clients it shows "Loading..." and for other it shows nothing.

Then again... sometimes it works flawless.

Any idea what the matter is here?
