Pages palette bug
You will find a file in the attachment, please open it. Now open the page palette. Now try moving the pages in the correct order of the numbers by moving the thumbnails. You will not succeed!
I reported this bug over a year ago and it still isn't fixed! (Indesign version 15.5.5)
Edit: Unfortunately I cannot attach an Indesign file. Please provide me with an email address so that I can send you the file.
