How setup 1 proxy 4G rotate for 4 pinterest accounts?

Hi all,
I’m new user and it’s hard to find any guide of the mass planer. I setup 4 pinterest accounts same 1 proxy 4G. I tried to setup one active account at one time.
Right now I only use the repin feature, so I set up the first account’s repin feature to work from 12am to 2am, the second account to work from 2am to 4am… When I look at the dashboard screen, I see that the first account is still working the sync page feature at the same time as the second account’s repin time.
I tried to setup time of the feature sync but unluckily …
I hope to find help or any suggestions.

I found where to setup the sync feature . I disabled auto sync.
