@saidevlinx1939 The workaround I've found easiest is:
install 'ftp server free' in waydroid (from the f-droid app store)
launch 'ftp server free' and tick 'anonymous access'
the URL to access the ftp server should be displayed.
switch to ubuntu touch, and open the web browser
visit the ftp server URL
bookmark it for future use
click on the file link you want to download to ubuntu touch.
It will download as soon as you click on it.
go back to waydroid and stop your ftp app.
If you prefer the command line, you should be able to do the reverse of the 'copy to waydroid' command to copy from waydroid:
In waydroid place the file to be copied to UT in the 'Download' folder
Open a UT terminal and enter for example:
cd Downloads
sudo cp ~/.local/share/waydroid/data/media/0/Download/myfile.apk myfile.apk
The file should now be in your UT Downloads folder
