LineageOS OTA upgrade not working

[lecrote]

I ask the same question here without any answer!
https://forum.xda-developers.com/lineage/general/lineageos-ota-upgrade-t3569304

I have succesfully intsalled LineageOS on my asus Laser 2.
Now LineageOS said that there's new version I tried to update trought OTA and its not working.
How can I update without losing data because I don't want to setup again all the apps (work and personnal)
I use TWRP recovery

Thanks

Dan
