cloud sync works incorrectly. (between cloud account and plex account problem?)

Hi. I just join plex pass.
I want to use Cloud Sync Service for my TV so join PLEX pass.
Have one Question.

I join PLEX with google account(A) and add google drive at Cloud Sync(B).
(A) and (B) 's google account ID is different.

There is problem.
my (A) account and (B) account (what I want to use) is different.
but (A) account’s google drive have files.
so although I correctly add (B) account
when seeing library, there is only (A) account’s google drive files.
I can’t see (B) account’s google drive files.

How can I do?

** sorry for bad English. I’m not good at English.

I’m not clear what you did. Cloud Sync does not see files you already have on your Google Drive. You need to sync the files to your drive, then you will see them. You can link any Google account to Cloud Sync, it does not have to be the same email as your Plex account. Maybe some screenshots would explain it better.
