I encountered an issue where libFLEX failed to load in springboard, but not in apps on iPad Pro 2020 (A12). It load fine in <=A11. I opened this issue on FLEXall initially because I thought it was a FLEXall issue, but seems like it's pointing to libFLEX's. You can see the response by dghost here:DGh0st/FLEXall#7 (comment)

But by checking the Makefile, it does seems there a flag for arm64e, so I'm not sure is the released version included it? Thanks.
