I've got the same, on the hunt for an answer.
The official Magisk Twitter feed does not look promising what so ever in regards to them getting passed the lastest implemented ways to detect system changes. Only time will tell... Lol
@Tulsadiver no, I neglected to do that since I was able to do so previously without ever having to... any idea how to do so at this point? do I need to wait for an updated image from your thread of https://forum.xda-developers.com/pixel-4-xl/how-to/magisk-modules-disabler-booting-magisk-t3990557 ?
hah! I'm in idiot running around with my head cut off. I just checked, I dumped that folder into the root and not into ramdisk! anyway, turns out the culprit of my issue was your mod to increase the notifications to 7! hopefully you can make an updated mod for this update when you get some time
any suggestions on how to fix this? updated to the Mar 2020, extracted the boot image, patched in Magisk, flashed, and rebooted like I have done with the previous updates, however once the device is booted up all I get is a black screen! device is still responsive as pressing the power button brings up a menu allowing me to shutdown or reset. flashing a non-modded boot allows me to use the device normally again. help!
No, not magisk props config. I linked the module he was referring to. Make sure during installation you hit the volume up key when it prompts you to at the end because you need to let it clear the gpay data.
