One Reddit user says that writing in the device is also slow on his device. A few reported that the issue persisted after a factory reset and disabling all Chrome extensions.
It’s not clear how many Chromebooks are experiencing performance issues after the latest Chrome OS update. Android Police He writes that the problem is mainly reported by Chromebook users with Council name “Grown” or “Hatch”. At the same time, not all affected people shared enough details about their devices. So it is not clear if the problem only occurs on these Chromebooks or not.
In any case, it is recommended to wait a few days before updating to this version of Chrome OS. For example, users can prevent the update by not shutting down their laptop, writes Android Police. Regular Chromebook users don’t have the option to turn off automatic updates.
