If you want to submit feedback to Fandom, please use this form. When it comes to the editor, you are definitely not alone. However, the old editor is not compatible with the new software which is why it was removed.

What software?

He was referring to Legacy, which was the old software FANDOM had been using for many years, which the old software is transitioning to UCP software, but critics of the old software saw that the Legacy software is outdated and it was years behind the latest version of the MediaWiki software.

To be accurate, the old software is MediaWiki 1.19 - which was used on legacy wikis, and the new software is MediaWiki 1.33 which is currently used by UCP wikis.

As was said, you did better send your feedback to Fandom staff, but also you did better explain the specific issues you are facing rather than demanding changes.

I send them a feedback asking for a change.

@HumansCanWinElves Yes, correct!

@Weg444 If you're reading to this, contact the FANDOM staff on how UCP can be improved.

I did send a feedback already. Hope they read it.

Ok

They said it's not possible to switch the wiki to the 'legacy' platform (this sucks). They said they expect to make rapid improvements and fixes to this new platform in the coming months, including reintroducing features from the previous platform (I hope that means something),

The part about being "rapid" worries me. Sure, it is great to get things out as soon as possible. But with Fandom there is a track record of "rapid" being a synonym for "very buggy".
