"Add integration" button missing

Hi everyone,
I recently installed the home assistant for the 1st time, trying to get some automation done.
The issue I face is related to the integrations, in the Configuration->Integrations the “+ ADD INTEGRATION” button disappeared. I have the installation since 3 days and sometime during this time something happened and the option is not there anymore.
Now, the thing is, this happens on both Firefox and Chrome, running on Ubuntu 16.04.
However, the option is there on another machine running the same OS version.
The option is there also on my phone running Android, in both the browser and Home Assistant app.
So the option is not there only on a specific PC, which happens to be my main PC.
I disabled add-blocks, cleared caches, have no firewall, ran out of ideas.
I’m running the version 2020.12.7 according to the Supervisor->System tab.
Any help much appreciated.

Maybe the account you are using is not an Administrator, but just a “user”?

Hi Christoph,
I do use the same user everywhere which has administrator rights, so there must be something else.

Regards.

I think I found what happens: if the window is maximized the button disappears. If not maximized it pops up again. I did scroll the entire page when maximized and is nowhere. If I remove an integration so that there is more free space on the bottom of the page it’s again there. Bug?
