They have to report it to topjohnwu and if its caused by magisk, he will fix it for sure. You will be one of the first to get the fix because I have Magisk Canary in the kernel.
You can try it with v1.4 Kernel update (released today with new updated Magisk ), but I dont think fix is included.
But using an old Magisk isn't a good solution.
And I don't see the point to use root vanced, if no root version with micro g is working fine. Use the apps of my screenshot above until topjohnwu fixes it. The vanced app I'm using won't be updated via the playstore
