Inkypen did all the work to bring up R from Q. I haven't tried BitGapps or NikGapps, but they work for most people, depending on how many gapps you want to flash as system apps. Personally, I prefer a minimalist gapps experience. I install all my Google apps as user apps since system app updates are installed in the /data partition anyway, not /system, so there is no space saving unless you flash a bigger gapps package that detects a Google app update in the /data partition and moves it to /system to save space in /data, but that's only useful if you install very many Google apps.Thanks @ripee It looks like I had somehow got a zip of Magisk 22.1 sources. Sorted now thanks.
Can you say why you recommend opengapps over the other options like BiTGApps or NikGApps for Android 11?
And this is such good work you and all devs have done with this ROM series, it is hugely appreciated.
