How to disable simple UI, cannot access the accounts after upgrade

[teomcam]

I just installed the latest version of Scatter onto my previous version. UI got simpler but I cannot access any of my accounts now. I can't find any guide to follow and fix the issue. Does anyone knows what below warning means? Is there any full version of scatter as it says can be used only with one account.

This key is not attached to your mnemonic phrase (words). It will not import when you import your words. You should save this key manually.
