Before i start my name is Red i'm one of the admins in YouTube Vanced Telegram chat Click here to join and after i got few people sending messages related to this issue i'll post 4 workaround solutions.

Me and [MENTION=6841137]Logan[/MENTION] made a small investigation about this and this is related to WebView and Chrome, Technically Chrome v74+ is causing Log In issues any other version should work fine.

Also Android System WebView is causing Log In issues (didn't test any version yet but v74 was confirmed to cause login issues)

THAT MEANS NO 75 BETA WOULD WORK, ONLY VERSIONS UNDER 74 WILL.

First Possible Fix:

1. Go to WebView app in the Google Play Store by visiting this Link . (in case there is no button to enable just disable chrome and try again , if there is no button still just continue)

You will see instead of install button another button which it says Enable and tap it.

2. Go to Settings -> Apps -> Chrome and remove all updates OR disable it which is better.

3. Go to Settings -> Apps -> Chrome and wipe data and cache

4. Go to Settings -> Apps -> MicroG and wipe data and cache

5. Go to Settings -> Apps -> YouTube Vanced and wipe data and cache

after you are done try to log in, in case you still couldn't force close Chrome, YouTube vanced and MicroG then reboot your phone and try again.

now if what i said above didn't work continue to 2nd fix and if it did actually work you can enable and update chrome it should all be fine.

Second Possible Fix:

downgrade chrome to any version other than v74, and do 3,4 and 5 from First Possible Fix

how to downgrade for devices that doesn't have pre-installed chrome v74:

1. Go to Settings -> Apps -> Chrome and remove all updates.

2. Go to this link.

3. Download any version that is under 74, i suggest 73,.....,69 not less.

4. Go to Settings -> Apps -> Chrome wipe data and cache and install the update you've got from the link above.

Third Possible Fix: Thanks to [MENTION=3253730]Darkat70[/MENTION]

Fourth Possible Fix: (For Android Q users)

roll back to Android Pie, Then use the workaround provided above and update back to Android Q. (Tested by one user and the user confirmed it works fine)

so what i've tried so far and didn't work:

Disabling/uninstalling/downgrading chrome and/or WebView on android Q (without using root)

if you tried everything and nothing seems to work for you in my opinion (completely up to you) is to root your device and switch to root version.

those are the current options for you until MicroG update their app

Over 90 users confirmed this workaround (over XDA, Telegram and discord) that it helped them out and the count is still going on :)

Explanation to why this issue happened and why it is NOT RELATED to Vanced Team:

as an example to make it easy for noobs consider you got a car and you need gas to run the car.

The car is YouTube Vanced and the gas is MicroG so if you want to log in you need MicroG app (talking about non-root version)

Google updated their sign-in from their server side and with chrome and webview having this new update and MicroG didn't implement the new update into their app it caused this sort of issue so this completely unrelated to Vanced Team this is completely related to Google and MicroG :)

Edit: we released a new microG update please don't use this method anymore and update your microG app
