Having trouble getting virtual keyboard to show up on iPad when bluetooth keyboard is connected

I bought an iPad case + keyboard that always stays connected. I’m finding that I can’t get the virtual keyboard to show up when I have my Bluetooth keyboard/case tucked away (I.e. rotated so it’s on the back of the iPad and can’t be used). I see a little arrow in the bottom right of the screen that some forums say can be used to bring the virtual keyboard up, however that arrow just disappears for me as soon as I click it. I updated to the latest software. Anyone else having this issue and know of a solution?
