Chromebooks Updates Stopped

[BarbSeib]

Our Chromebooks won't automatically update to v135.  My entire fleet is stuck at v134.0.6998.183.  They allow automatic updates until 2030 and the admin console I is set to allow updates "use latest available update". I used the Chrome Recovery  Utility to jump to v135 for a few but I don't want to do that for all of them. Any suggestions as to what is causing this restriction?

What is the Stable version for this model listed here?

Based on that, see if you are dealing with the extended updates lifecycle.
(Although if you have 135 recovery images available I'm not sure this is the case for you.)

It says my stable version for Acer Chromebook 712 [C871] should be 135.0.7049.120 however they won't budge past 134. I do have extended updates. Still nothing.   Same thing for my Acer Chromebook Spin 511.

No one else is having this problem with Acer Chromebooks?

My Chromebooks have an update auto policy of June 2030.
