I am so sorry you are experiencing an error, and thank you for reporting this. I will be sure to make a note in your arrount so that our developers are aware. From what I understand, this error appears to be happening when editing an image while working on an email, is this your experience? Customers have found that there are no issues when editing images directly in the Library. If you haven't accessed editing options from the My Library page, see this detailed article: Edit Images Using Adobe Creative SDK. I hope that is helpful in the meantime!
Having the same issue. Using Firefox. Never had an issue before. Now with new email platform & editor, can't save changes in photos & no html option to tweak emails. AND CC runs $25 a month more than everyone else. Remind me why I do business with you again?
I am very sorry to hear you are also experiencing this issue! I also appreciate you providing some feedback on your experience with the new editor. I have tracked the feedback in your account for our developers to see. If you are able I would be happy to submit additional feedback on why you want access to the HTML. What kind of tweaks are you trying to make?
As for the photo editor issue, have you tried another browser just to see if the issue replicates? I certainly don't want you to stop using your preferred browser, but it would be helpful to know if it's local to just Firefox for you. As a workaround, editing the image from the Library tab appears to work for other users. I know our developers are researching why this is happening and I can have you notified when a fix is in place. I sincerely apologize for any inconvenience this has caused!
