Yes it's a tough wait. My first course was 2 days in review but we weren't so affected by Covid 19 then and with people working from home, making it harder to process.
Now my second course is still In 'Review' going into its 4th day. Trying to be patient and using the time to explore any additional marketing ideas. The worry is if something pops up as needing a fix and then back to the beginning to queue again for another review process. Hopefully we will hear something very soon.
