When I connect an apple keyboard to my iPad, I have some problems with the block

<key [ v] pressed?>

But the block

when [ v] key pressed

Works normally

To go along with that, the arrow keys do not seem to work as triggers.

when [down arrow] key pressed

does not seem to do anything when working on an iPad. Other keys, such as space and the letters do work correctly.

Thanks for these reports. We're still working out the kinks for Scratch 3.0 on mobile, but we'll experiment with iPad keyboards and see if we can see what you're seeing.

Have the same issue:
CR (can reproduce) - iPad 6, Safari on iOS 12.1, Logitech Rugged Combo 2 keyboard case.

I am also having arrow key issues on some iPads with Logitech Rugged Combo 2 keyboard case as well.

key pressed blocks not working for arrow keys but space works. IOS 12.0.1

I can’t press space because I only go on the iPad.

Make sure you're on the latest iPadOS: 14.5.1 or 12.5.1 if it cant support 14.5.1

Im trying to play my keyboard controls on my Amazon fire tablet HD 10, but it isn't working, could you fix it for Amazon tablets too?

If you can make projects more playable on mobile, often I would do a joystick (for moving players) and buttons for whatever else.
