[Bug] Cannot send files like PDF, only images

[t0msk]

I have Pixel 4a, and I paired it with my computer, problem is that when I try to send something I cannot send files like PDF, but when I send from PC to my Android drviče I can send any file format, do you know how to solve it?

There is screenshot:

I have similar issues with my android device.
