Cannot cancel subscription

[Ualikhan]

Hello.

I cannot cancel subscription to Acrobat Premium. I followed the instruction given by Adobe support consultant. But I cannot see cancelling button. 

They sent me this instruction:

     Open Adobe Acrobat app

·         Click on “Settings” (human like icon on the top right of Home page)

·         Tap “Subscriptions” and then Tap “Manage Subscriptions”.

·         You are now in Play Store. Choose the item that you want to cancel and then tap “Cancel Subscription”.

I followed the instruction, but tapping the button "manage subscriptions" I could not find "cancel subscription" button. (It shows me only "start" button.

Help me please.
