Even tho I didn’t set up any client billing in all my sites, there is no Switch to Workspaces button in the alert, but the warning to disable client billing.
Hey Yan, I had your problem and was frustrated too as I disabled ALL client billing and was seeing this notification.
Basically, even though you may not have ‘client billing’ on any website, you need to actually disable your account to be ‘verified for client billing’. Here’s how I just fixed it:
Go to your main account page settings and look for the “Billing Tools” tab. There, you will see your “client billing active” - cancel/delete that. It should work. Hope that helps, it was bugging me too!
