My Box Sync (v4.0.8088) no longer has the CHANGE LOCATION option. There is now a OPEN LOCATION option. See my vid showing this problem please. https://drive.google.com/file/d/1P4fCdbSB6Y27f_YYP1uzpDIXIe-tsvWH/view?usp=share_link
I have Logged out of Box Sync, and back in, to see it it showed up. No.
Plus much is OUTDATED on this page to the current App. https://support.box.com/hc/en-us/articles/360043696674-Modifying-the-Location-of-the-Box-Sync-Folder
