I just downloaded DT to my MacBook air. The option for iCloud sync isn’t even available to me. The only options are dropbox, cloudme, local sync store, and webdav. What happen to the iCloud option?
Select iCloud Drive in System Preferences > iCloud (or Apple ID if you’re running macOS 10.15 Catalina), click the Options button to the left, and enable DEVONthink
Thanks!
You’re welcome 
Hello,
Here’s the issue i’m having now. I enabled iCloud from the preference pane and confirmed on iPad and iPhone as well. It’s like the iCloud option just disappeared or something…
Does it persist after a machine reboot?
If so, hold the Option key and choose Help > Report bug to start a support ticket.
Thanks for the quick response!
I’ll try a reboot one more time (I reinstalled as well). If no, I’ll do an error report. Thanks!
Restart worked. You’re the man!
Glad to hear it!
