change directory

Trying to change the directory of the sync location on 1 device. It’s grey out, so I tried to delete it and recreate it with the same folder ID, but as soon as I connect to another device, it goes back to the old setting/location.

Does it mean I will have to delete the folder ID in all devices and recreate a new one?

Did you restart Syncthing between folder deletion and folder addition? Could be, that for some reason something is “cached”.
