Adding 3rd device onto plan but upgrading to protect plus

I have 2 devices on basic plan. Just paid annual subscription until March 2021. How do I add a 3rd device and also upgrade to the protect plus plan. I want to pay the difference in cost to the £80 not £80 plus the subscription of £49.98 I have just paid.

Hi @Catlc! This should be possible through the “My Plan” section on Check out our help center article about protect plans for information on how upgrades are prorated or handled. If you need any assistance with this change, our support team will be happy to assist! :slight_smile:
