Did you use Magisk uninstaller? I might just skip it. I don't want to because its a pain to setup all the modules after.
[OnePlus 5T  Guides, News, & Discussion] tcat007:
No, just wiped caches. Kept booting back to TWRP, but then I remembered I had EX kernel on ob20. Reflashed EX 4.0 and rebooted normally. Shouldn't have had to do that since ROM would have overwritten anything kernel. OOS has been strange on clean and dirty flashes.
[OnePlus 5T  Guides, News, & Discussion] sjancura:

Dirty flashed without any problems. But YMMV.

- flashed latest magisk uninstaller

- flashed rom (deleted compatibility zip)

- flashed magisk 18.0

- wiped cache and dalvik

- reboot.

The only annoying thing is for some reason magisk manager doesn't appear on my app drawer. So I just manually installed the apk and it will appear again. Rooted and passed safety net and certification. I also still have my fingerprint and pin.

Let's see if OP fixed the random stutterings I experienced on the previous build.

You don't have to. If you update from previous beta or don't flash from TWRP. But if you use TWRP you have to.

It's a oos checking system thing for security reasons.

[OnePlus 5T  Guides, News, & Discussion] fraz14:
I think [MENTION=774530]Chaplan[/MENTION] means there never was an notification led color per app customization setting.
[MENTION=4158306]tcat007[/MENTION] your screen is with on/off switch. Not with per app customization.
[OnePlus 5T  Guides, News, & Discussion] Chaplan:
Yes, that's what I meant.

The "per app notification" setting on OOS only lets you enable/disable notifications on a per app basis.

What was asked for was LED color customization on a per app basis, something that unfortunately was never brought up on OOS.

My go to custom ROM has it and I use that feature quite extensively.

On OOS I rely on the shared app to mimic it, not ideal, I prefer it built-in the ROM side as opposed to the app implementation, but the app works very well on OOS.

Since we have LED, we should use it to the best extent...

[OnePlus 5T  Guides, News, & Discussion] Chaplan:
Ok, so I have tested Pocket Casts for 25 minutes and made 2 calls in between.

My BT works pretty good with both OB1 and OB1 Hotfix builds.

My head unit is a Ford Sync II.

From past experience on the OP3 where similar problems were reported, adressed and solved with:

"Compatibility optimizations for various bluetooth devices."

on the changelog later on with new OB releases as I recall reading.

My main issue at the time was metadata not passing to the Unit. This works for me on the 5T already.

Bug reports, on the official channel with the problematic head units models probably would be helpful at least for OnePlus to acknowledge the issue as they did in the past.

Well, this is OB, so some quirks here and there are to be expected.

Not that stable doesn't fall on the same route from time to time.

I do hope this gets nailed pretty soon for all of you.

I have tried to

1. flash the either above 3 twrps,

2. then flash OB20 or OB21 without compatibility,

3. then flash magisk.

If I do as 1, 2, 3, then I will reboot into the twrp, my data is in encryption.

If I do as 1, 2, then I will succeed but when I reboot, the twrp is lost, it was flashed with original recovery. So I redo 1, 3, it reboot to twrp.
