Zephyr plugin lags lead to the impossibility to working with the tests!

Since yesterday, February 19, using the Zephyr plugin in Jira Cloud is impossible. Test cases, executions, and cycles fail to load.  After attempting to open the executions, it was just an unending spinning.  And based on the queries in this forum, I can see that I'm not the only one with this issue.

 My coworkers are experiencing the same issue after trying several browsers; We need this to be fixed as soon as possible.
