No Longer Able to Access App Maker

I've been using Google App Maker for a few months now, but tried to log into an existing App today and am getting this error:

The published app still seems to be working. But, I tested two different admin accounts to try and edit it and both get the same error. I looked under the G Suites Admin Panel and don't see App Maker in the G Suite Apps or Additional Google Services section.

Who do I need to contact? Should I submit something to the Issue Tracker?

If App Maker is no longer showing in your Admin Console then it seems there is a problem with your G Suite account. There are other reports in the App Maker Google Group from other users who are also reporting something similar hence I believe this is a bug. Please don't use Issue Trackers since this is mainly used to report bugs or issues found inside the App Maker service.

You must contact G Suite Support to report this since this an issues associated with the services inside the Admin Console. There is an App Maker Team in G Suite Support that will be able to help on this. More info on how to contact G Suite is available here https://support.google.com/a/answer/1047213
