I am having a consistent issue with the keyboard shortcut on macOS Sierra.
I have bound the Clipboard History Shortcut to
SHIFT + APPLE + V
(I have used this with another app for years - it is basically hardwired now)
However, after a reboot the shortcut does not work.
The only way I have found to get it to work is to go to
ADVANCED > SET SYNC FOLDER
Then change the Sync folder
It is saved in Google Drive synced using inSync (not Dropbox - I saw a thread saying this could be an issue)
What i have been doing is changing it to a tmp folder, then changing it back.
This drives me a little nuts - any help much appreciated
