Android Question [Solved] Logs no longer showing over USB, but do over B4A-Bridge

[swChef]

I updated to 9.80, java11, androidX, did jetify, etc followed the instructions.
Have rebooted phone, PC, renamed app, tried several. Checked for a developer option logs enable setting. Turned off dev options, back on, reselected all necessary options.
Did not get anything showing in the Logs window except for: Logger connected to: LGH872d8eaxx5b
After I loaded an app via B4A-Bridge, then Logs would show via the bridge, but still don't via USB.
Can install an app, and can debug an app, over USB.
Been using this phone for a couple years, no issues prior, several B4A releases used.
Tried another phone, still only: Logger connected to: LGH872da28xx31
Tried going back to the earlier java. No change.
Probably forgetting a thing or two I tried.

There is nothing bad with using B4A-Bridge instead of USB debug mode. There are actually advantages for using B4A-Bridge.

You can check if the logs are working by running adb logcat from the command line. This is an Android SDK tool.

Installed Android Studio. Logcat works there.
But still not with c:\android\platform-tools\adb.exe. (adb logcat) in a cmd window. Nor with the studio's install of the platform tool adb.
What does work is to open a shell (adb shell) then command (logcat). And (adb shell -x logcat) works, too.
Turns out the latest update to platform-tools exposed a problem with LG devices. [last update to my LG device was Jan 2019, at Android version 8.0.0]
gagallow7's answer has a link that works, and provides the replacement instructions to put it into effect.

Not sure yet how to downgrade platform-tools using B4A SDK Manager.
Searched on downgrading platform-tools and found this result.
Using the instructions at the last link (this result) above in stackoverflowuser2010's answer I downloaded 28.0.0 for windows via link, renamed my old c:\android\platform-tools folder, and extracted the zip file to that path.

Now B4A IDE's log window works again.
