Such an elementary error. I downloaded the new Microsoft Translate app on the iPad and was wondering which folder to put it in (that’s how I roll, everything goes in a folder unless it’s on the dock). I left it where it was and proceeded through several dozen Apple News articles and one made mention of 13 apps permanently in the dock to the left & 3 most recent apps to the right.
Here’s the error. I’d thought you could only have 12 permanent dock-residing apps. Problem solved.
