Hi @MattP9534 ,
Thanks for taking the time to detail the steps you were taking and your browser - that was really helpful.
This is interesting, I was able to get it to work also in Chrome, but I ran through it a few times and during one of the times I ran into the same problem you described. I haven't been able to get it to happen again though. When inserting you're in the image library you have the option to either hover over the image you want and click Insert, or you can click on the thumbnail of the image which opens a different view that also has an insert button in the bottom right corner. Do you remember which way you tried, hover over or click? If you can still get it to happen, can you close the insert image window and try it again the other way to see if that works?
I'll keep testing to see if there is something I can consistently reproduce to get reported.
