Please describe your issue below:

Want to upgrade to Ubuntu 22.04 but the image is not available for EMMC-storage.
I have tried making costum images, or using the standard image for SD-USB, but then the Ethernet port of the extension board does not work using the overlays defined in /boot/env.txt
When will this official Ubuntu 22.04 image be released for eMMC compatibility?

Thanks in advance!
