Wow, this is really bad, I tried on ToT and can repro this every time. It seems the folder name is not synced to backend.

Stable 66 is about to hit. Still an issue on

Google Chrome	66.0.3359.137 (Official Build) beta (64-bit)
Revision	0
Platform	10452.74.0 (Official Build) beta-channel caroline
Firmware Version	Google_Caroline.7820.356.0
Customization ID	SAMSUNG-CAROLINE
ARC	4734322
JavaScript	V8 6.6.346.24

This is the same issue as 830985 which was fixed in M67 as a side effect by issue 828209

This is a very basic issue which you should not really expect 

When is this going to be fixed - Version 66.0.3359.181 (Official Build) (64-bit)

Highly unlikely to be fixed in version 66. Change your channel to Beta or wait for stable to hit version 67.

Assuming that the issue has been addressed in 67.  

I still see the issue (and others) on Version 68.0.3416.0 (Official Build) dev (64-bit)

Version 66.0.3359.181 (Official Build) (64-bit)
It's not fixed yet.

It's working for me now on Acer R11 latest update. However, the folders and icons within are not showing until you click on it. The folder labels have been staying after a restart though.

My experience is exactly as comment 13 (folder labels now staying after restart but folders/icons not showing until clicked).  On Acer R13.

It appears to be fix on Version 68.0.3431.0 (Official Build) dev (64-bit) running on a Pixelbook

I'm still on .158. What's that mean?

It's not just the folder names.

Changes to the arrangement of the folders within the Launcher window aren't preserved.

Changes to the arrangement of the apps icons within the group's windows aren't preserved.

Changes to the composition of the app groups aren't preserved..

So, if it is not fixed in beta 67, and it is fixed in Dev 68...it stands to reason that it will won't be fully fixed until at least stable 68 (hopefully in both 32 & 64 bit versions)
