On 2 servers in 2 seperate clusters I have installed Kibana 7.7 .
The thing is, when I start and go to 'discover, all is ok (except for an error message I have a seperate topic for). After initial start I am greeted with a small welcome message that stays for 5 secs and then disappears.
However, when I go to 'management' and then go back to 'discover' nothing happens. Even if I reload the page then, I get no 'discover' page on screen , it just stayes white. I can go to visualizations' or 'Dashboard' and the same as with 'management' happens.
BUT... If I go to canvas, Kibana appearantly reloads (I do have to say, it is slower than 6.x by the way),and shows the message again.
If after that, I click on discover again, Again kibana seems to reload again (according to the progressbar) and I am greeted again with the welcome message. But also the time to show (top right of the screen) is reset to 15 minutes from whatever I set it to earlier.
And the same like THIS happens when I go through 'APM' or 'maps' or 'Logs'. Everytime I open a page which starts with kibana logo and progressbar I can after that open 'discover like it is the first time I enter the site. But If I go through a page that is not loaded via a progressbar, discover is not shown.
After I change the time to show to e.g. 15 days, when clicking another page in kibana, I see that the time in the url parameters is set to 15m again.
What is happening here? Is this a bug or am I missing something?
Kibana 7.7 is installed against Elasticsearch 7.7 in Centos 7.7 (accidental ) and runs on a VM with 16GB Ram and 4 cpu's
