Zephyr plugin unaccessible, barely able to work with the executions, creation, editing test cases

Starting from yesterday (8 Aug) there is almost impossible to work with the Zephyr plugin in the Jira Cloud. Yesterday I was able to open executions and test cases, but only after waiting minutes to load a page. The situation is even worse today, the test cycles, executions, and test cases even do not load. Just an endless spinner after trying to open the executions. And I see that I am not the only one who has such a problem according to the questions in this community.

Tried on different browsers and my co-workers have the same problem, please fix this ASAP
