I had come to the Atlassian forum hoping to learn that my untenable difficulties with the new Confluence editor were my error, but now I understand that this edit is truly a ridiculous mess.
Many of my co-workers are running into multiple issues with the new editor, since it became the default editing in the past two weeks. I have instructed them to use the old editor, but now I am very concerned because the old Blank Page icon now says that it's going away soon! When? I have no idea because even the warning was ineptly worded. Doesn't anyone at Atlassian check their work? It says, "In the upcoming weeks, the old editing experience will no longer be available as a..." ... what? If the warning wasn't so wordy, I'd know when it was going away!

Serious! I hope Atlassian is planning to hold off on deprecating the old editor because the new editor is almost unusable! Repeat, UNUSABLE!

Some threads are calling for the product manager involved to be fired. Well, that's pretty severe. LOL
The real blame should be placed on the leaders who decided in the go/no-go decision to launch this inept editor. It would be more than just a single product leader that was involved in that stupid decision.
At the very least, Atlassian should issue a public apology for this gross lapse in judgement, return to the default old editor, and don't dare force a change on their paying customers until they can answer YES these three simple questions:
1. Is the new editor better in all respects?
2. Does the new editor solve a problem or problems?
3. Switching to the new editor will not cause customers any pain, with respect to compatibility issues with the old editor?
How about it, Atlassian?
