Hi @Varius67, 

Welcome to Trend Micro Community!

Sorry for the hassle this has caused! We're aware of the issue where you're being redirected to a "Consumer" page, and we're on it. It's great to see you managed to sign in successfully.

After checking your account, it looks like your license is limited to just one device. So, you won't be able to add or remove any devices at the moment.

If you'd like to learn more about deleting or adding a device, check out these guides: How to Remove Trend Micro Protection on an Old Device and How to Add a Device to Trend Micro Subscription.

Hope this helps.
