On Arrow OS is working too. Banking apps, payment apps, streaming services....
The thing is usually you cannot damage or erase L1 certification by resetting, formating or reinstalling the OS.
The L1 file is stored in your Persist Storage so it's protected from normal user intervention. You have to really mess up your phone internal root structure in order to lose the L1 certification.
All those people crying about losing L1 they either did not followed recommended procedures to install their new ROMs ( there are specific instructions for each particular ROM), either they were messing around with things they did not understand. You can do alot of damage with TWRP and ADB. Both of these tools are like a scalpel. You have to know where to cut in order to not damage or kill your phone
