Is it only me having issues with OTA upgrade? Could it be because of the TWRP version I am using? In order to upgrade /e/ I always have to do it manually using adb sideload from within the LOS Recovery and then restore TRWP using the same method. This in turn impedes the completion of the upgrade. In other words, the OTA upgrade of /e/ wipes my TWRP and installs LOS Recovery instead. At that point, I can choose to launch recovery, which instead of TWRP, that was previously installed, is Lineage OS Recovery. The initial preparations executed while Android is running seem to succeed, but when I reboot it gets stuck at the bootloader. In my setup, that in all ways work perfectly, when I try to upgrade /e/ using OTA, it always fails. This is a necessary detail because in order to install this OS I had to flash a more recent version of TWRP, specifically twrp-3.3.1-16-enchilada-installer-mauronofrio.zip.

I installed /e/ starting from Android 10 and went through various issues before finally succeeding, see Install /e/ on OnePlus 6 running Andoroid 10 Hello there, I am happily running /e/ since over a month on my new OP6.
