Syn Member and subscription as global from WP Multisite Networking

Info:

My site is Membership directory based where user sign up, buy services (subscription) and then have access to Member directory. I am using Ultimate member n addons and woocommerce Subscription plugins for these.

my site is using WP Multisite networking system for multi languages without any difficulties.

domain.com/eng

domain.com/Rus

Problem:
When user who registered and activate subscription by buying it from English site switch to Russian site then NO Purchase and no user who registered in eng show!
I want to set global users with custom roles i created and subscription no matter which child site they are using, their membership and subscription should be show.

i am not good in code so kindly help me with some references if possible.
