[SOLVED] Hide/show TAB depending on CB Subs - NO reaction

Hello !
My environment - CentOS 7, Apache 2.4, PHP 7 and all latest CB and CB Subs including latest
cbplug_int_cbsubsfieldstabsprotect-4.1.0+build.2016.09.20.07.58.14.931a0995b.zip

I tried to create an empty TAB to show/hide the one depending on free CB Subs plan
But TAB is visible anyway

The following steps done
1) Created empty TAB with name Coupon
2) Created free CB Subs plan
3) Under CB Tab Management -> open tab Coupon -> Integrations -> CBSubs Fields Tabs Protect

1)
A. Tab availability by Owner's Subscriptions (I tried both)
- Yes, CB Subs control tab availability
- Yes, CB Subs control detailed tab access

Owner Plans controlling tab available in profile -> set to free-test plan

2) For Profile owner himself:
Still Available for Profile Owner himself -> No: profile owner himself is also restricted

Basing on descriptions I understand it must control when a Tab appear or disappear on user profile depending on subscription.
But actually I see no matter if a user subscribed to free-test plan or not subscribed - anyway Tab Coupon is visible.

Please, let me know an idea how to manage that.
Regards,

If it's a free lifetime plan ensure free lifetime plans are configured to create subscriptions within CBSubs > Settings > Global. Also ensure CBSubs Fields Tabs Protection within CB > Plugin Management is public and published. Note moderators are exempt from this protection unless you use detailed mode and enable it also for moderators.

Thank you for the hint ! Problem solved.
Yes, I've missed to configure free lifetime plans to create subscriptions within CBSubs > Settings > Global.
When done - now Tabs appear/disappear depending on subscription.
