I can confirm the problem el_pinguino and gwengui describe above. I just attempted to install Waydroid using Waydroid Helper on a new installation of UBPorts on a Pixel 3a. The installation seemed to be successful and the phone rebooted. The Waydroid icon is there, Waydroid launches, the logo appears and the little blue wheel turns, but Lineage does not open. Please pass along to the powers that be that this installation method is still buggy. Thanks.
