I started using QBO this year. I have two separate companies, but somehow along the way, I activated Accountant View. How do I deactivate Accountant View?

Hello mike-cooke-e2eme,

Welcome to the QB Online family! I'm happy to learn you're taking advantage of the powerful features offered in the program. Don't worry, I'll be happy to point you in the right direction so you're back on track with your work. 

To get started, it's important to note that you're not logged in as an accountant user on the account. If you're logged in as the accountant user, you'll have a different interface as opposed to logging in as a company admin or a regular user. I recommend checking the users on your account by clicking on the Gear icon > Manage users. From here you can see the types of users you have on the account. In case this issue persists, I recommend logging into your account using a private/incognito browser window and let me know what happens in the comments below. 

Since you've just started with QB Online, here are some helpful tutorials/webinars you can check out in order to cut the learning curve. Let me know if you have questions, I got your back.
