If you download the OTA update package and install it then there shouldn't be any issues with losing your data. I have been using this rom for over 6 months now and I updated to every single monthly update from the OTA update channel.I have installed and successfully used LineageOS19.1 : 19-20220707-UNOFFICAL-dreamlte. The system suggests me to downlaod and install more recent versions of LineageOS19.1. What is you advice ? Does is worth it ? Any risk to lose data/app ?
