I only have the one account, and can definitely see the same list of all the other providers.
Changing the time zone didn’t seem to make a difference, the pCloud and CloudMe providers still gave the same Unspecified Error.
I’ve sent a diagnostic from this client (PC Name: Jaguar) just now.
EDIT: Have also now sent one from the laptop (Ultrakitteh) - as you can see below, it has a bunch of providers working, and they synch just fine, but there’s no placeholders for the missing ones.
(Note that the FTP placeholder here was created manually as referred to in the other thread, and both didn’t appear manually, and gives the proxy error when used)
