Dell Optiplex 7410 AIO will not update ChromeOS version

In our FSC, we have four Dell Optiplex 7410 AIO computers running ChromeOS Flex. When I click on About ChromeOS, then Check for updates, it appears to download the new version. However, when the download is complete, it says, "Your Chromebook is up to date", but remains stuck on Version 141.0.7390.115.

I have tried updating them to the latest Dell BIOS, 1.31, and these computers are still stuck on Version 141. Will I need to reimage these four computers?

Also note that our older four Dell Optiplex 7460 AIO computers have updated to ChromeOS 142.0.7444.234, but the four newer 7410 computers do not want to update. Our only Windows computer is an Optiplex 7410 that has its Chrome browser updated to version 143.

I have opened a ticket with FSC Support.

FSC Support's answer was that if we are not having problems printing or any other problems, then we should not worry about the ChromeOS Flex version.

My OCD is raging hard on this one. I will wait and see what happens over the next month. If the older 7460 computers continue to update beyond version 142, but the newer 7410 computers remain stuck at version 141, then I will call FSC Support again and get their approval to reinstall ChromeOS Flex.

I powered on all PCs in my FSC today. The older Dell Optiplex 7460 AIO PCs immediately updated to ChromeOS 143. The newer Dell Optiplex 7410 AIO PCs once again appeared to download the new version, but then stopped, saying ChromeOS Flex 141 was the current version.

So I followed the standard procedure of creating a ChromeOS Flex installation flash drive, performing a clean install on the PCs that refused to update beyond version 141, and enrolling them into the FamilySearch managed account. After installation, the PCs were running version 142, which immediately updated to version 143. Problem solved!
