How do I switch back to the old design?

[Андрей Колесин]

Today my trello interface automatically changed to the new design.
I use an extension that does not work with the new design.
I do not have a button to switch back, which my other colleagues have.

Hi @Андрей Колесин 

The new design is being rolled out in phases to different areas and account levels. After a while, your colleagues will also have this version, with no option (for now) to revert to the previous version.
I recommend expanding the information with the name of the extension and including a screenshot (if possible). This will increase your chances of receiving help through this forum, as this is a free account, which will not provide technical support.
Best regards.
