We are using GitHub branch source plugin to build PullRequests and publish GitHub checks.
About a month ago, problems began with GitHub checks, which are only getting worse. A problem constantly occurs when the PR job is successful, the logs show that the check has been published successfully, but on GitHub the check is in the Pending/Queued/In Progress state. Sometimes Check shows the correct result but rolls back after a while. Please, see screenshot

Issue is not related to GitHub outage that happens sometimes. And it extremely blocks our work.
If you need any additional information, I will gladly provide it.
