Good grief, YES. Hope the workaround works; otherwise, this will utterly trash about a year's worth of work if iFrames can't be a readable size.
Hello there, @ckofeldt ...
I wanted to check in with you because I've noticed there hasn't been any new activity in this discussion thread since June 8th. Have you had an opportunity to review the feedback you've received from both stefaniesanders and @emily ? Did either of those replies help to answer your question? Or, are you still looking for some help with your initial question? If you feel that one of the above responses has helped to answer your question, please feel free to mark it as "Correct". However, if you are still looking for some help, please come back to this thread to post a message below so that members of the Canvas Community can assist you. For now, I'm going to mark your question as "Assumed Answered" because we've not heard from you and because there hasn't been any new activity in this topic for over two months. I hope that's okay with you. Looking forward to hearing back from you soon, Courtney!
It has since been fixed. However, if you implemented the workaround above, you have to go back an un-implement it, and reset the values the normal way because when it doesn't find height/width tags, it inserts 150x300 automatically.
