Why is my iPad not accepting screenshot images from my Mac?

I frequently use the Universal Control feature from my Mac, the 27in, to my iPad Pro 5th gen, and recently, when I take a screenshot from my Mac and drag and drop to my tablet, the image won't appear. To be clear, I see the mouse going from the Mac to the iPad, and I see the image floating on the iPad, but when I release the image, it does not appear on the screen. I have the latest update, the Sonoma 14.4. I've searched everywhere and I honestly don't know what to do. I am not good with tech, but I don't know what else to do. In addition, I don't know if this is relevant, but my Mac does not find my iPad on Bluetooth and I have tried everything as well. I restarted it, and everything and nothing.
