I have had this problem intermittently where I cannot sync a database to Dropbox. Now I find that I cannot do anything as listed below:
Sync with Dropbox just nothing happens, if I hit the cancel X in the bar it reports the operation was cancelled.
Clean Location: Nothing happens at all
Export Local Sync Store; it attempts but the local sync store is empty and as above the progress bar never finishes.
Remove and reset Drobox sync location. No help.
Rebuild database, then try to sync no help.
Of course I have verified and repaired all. I am stuck. Not sure what else to do or try?
Thanks for any help you can provide.
