Can't Add New Watched Folder

Hello @natespa and @jcd666, welcome to the forum and thank you for bringing this up, and sorry for the delay in replying.
This looks very similar to something we’ve investigated in the past.
Not to ask a gazillion questions potentially useless questions and wasting your guys’ time, would it be possible to check if the below advice worked for you first?

If it does not, we’ll do our best to figure out where the problem is and see what can be done about it.
Hope this helps.
Thank you again,
Yuriy
