@zemekis148 Sorry to hear that, but it sounds like something wasn’t quite right. You should never see it more than 3 times. If you dismiss it it shouldn’t show back up for 2 weeks, then another 4 weeks, finally never again.
If you click already did it should never show again either.
The code used for those requests is used in at least a dozen popular plugins and we rarely see complaints like this. Almost always due to a JavaScript error preventing the dismiss Ajax event from triggering or a PHP error causing it not to get saved. I’m all cases it was caused by other plugins or themes.
Can you try installing the Health Check plugin. Then go to plugins page and choose Troubleshoot for the Content Control plugin and see if you can dismiss it that way. If so it confirms the above.
Otherwise we would love more feedback on exactly what you were seeing.
