How do I add an add-on to an existing subscription?

How to expand your subscriptions with add-ons:

Log in as an administrator in your My tapio company account.
Navigate in the menu to Company Account ⚙️ -> Subscriptions & Payment Methods and scroll down to Subscriptions.
Select the subscription you want to expand with add-ons and click on Change subscription within the subscription.
In the dialog, under "Additional units", add the desired add-ons using the respective +.
Agree to the terms of use and complete the purchase via Change with cost obligation.
Check: Some add-ons need to be set up. Check in My tapio under the menu item Apps to see if your add-on is ready for setup.
