Here’s a trick I learned to stay at whatever version you are most comfortable without getting auto updated by AG’s latest version.
Click settings (gear icon). Click Editor Settings
Type “update mode” in the search field and select “manual” from the dropdown menu. You need to restart AG before it can take effect. Sometimes require a few restarts.
So far, I find the most stable version for AG is version 1.20.6. So I stayed at this version.
