I see this is an old thread, but it popped up in my search to solve this same issue.
The xml solution works great, but with one side note:
After you re-import the xml, it creates a duplicate sequence with the same name as the original. So, if you have “Sequence 1” already open and the xml file creates an identical “Sequence 1” in the browser, make sure you are checking the correct “Sequence 1” for changes.
I also thought it wasn’t working as was reported by others here, but then I noticed the duplicate. Might save others some time and confusion.
