System Android Version: 10 Custom ROM:lineage-17.1-20210328-microG-guacamole

Additional context -- fresh install of LIneageOS -- PayPal app installed from aurora -- Magisk v22 used to hide root (magiskhide)

@piet8stevens What happens is SafetyNet check fails, and since you have root, microG has nothing to do with it. Unrelated to this repo, but try Universal SafetyNet Fix + MagiskHide Props Config + HiddenCore. Also, after every reboot whitelist "microG DroidGuard Helper" from MagiskHide. Most-likely this won`t solve the problem either, since most banking apps require STRONG check and these modules grant only SIMPLE check. What can help is download a repack without root check (never do this with banking apps!) or repack it yourself with Riru server.

Version 7.38.1 works fine on microG. Seems like Paypal integrated safetynet in its newest release, before that it was not a problem. You can grab the older APK and use it just fine, but you should ask yourself if you want that, since it is a banking app and older versions may contain unfixed bugs.

Thank you for this feedback. It probably means that to get PayPal to work, more customization needs to be done in microG (magisk modules or specific settings). I am not going to do that for now because I cannot spare the time.

And I think you are right to raise doubts about using older versions of banking apps.

Just tried this on a clean install of LineageOS for microG (with PayPal from Aurora), worked w/o issues, not even Magisk.

@piet8stevens Everything should already be fixed on the latest version (v0.2.23.214816). Please test.

@ale5000-git it still doesn't work.

@GarondEisenfaust Does your device pass SafetyNet?

[GarondEisenfaust]

Yes it does
