Mann you gots me searching for a file that don't exist, lol. Kidding (sorta), but if you read my above post, release of v2.0.0 we clearly knew about, and if you follow in the Proton Telegram or are a Patreon, you also can see the announcement for v2.1.0..
You said
v2.4 -- with all that's going on with A12 on the horizon and nature of safetynet, and all the SN test .zips floating around, this was obviously a confusing egg-hunt. Thank you for clarifying it was a
typo, and I kindly ask you edit your above post to say the correct
v2.1.0 if you wouldn't mind.
I actually found
safetynet-fix-v1.2.0-MOD.zip to be enough for myself for things to work. However I am still on August update, no idea how much of a factor this is playing. (I wasn't using a specific module) as I was using the SysUI MOD found in themes section with the SN fix baked in. So I had to remove it from the MOD.zip, which I finally got around to so I could test.

And now back to our regularly scheduled programming ...
