I am the Primary Admin for 3 companies on QuickBooks line My Switch Company button has disappeared from the Profile list this afternoonHow do I get it back?

Hi peggy-writingwes, thanks for posting on the Community today

We're aware that some users are unable to access the switch company function in QuickBooks Online. 

This issue has been raised to our investigation team who're working to restore the feature. We've added you to our investigation with reference INV-111442 so that you'll be notified by email once fixed.

In the meantime, please use the workaround of logging out of QBO completely and logging back in, before selecting the company you want from the account manager (click the blue initial > Manage your Intuit Account > Products & billing > Select the company from list > Go to QuickBooks).

Thanks for your patience while we work to rectify the issue. We'll be here if you need any further support.
