It's now possible to get the correct GTM Container Version Date as Annotation Date.
Copy 08_Annotations-GTM.gs Apps Script and replace that Apps Script in the Google Sheet:
https://github.com/Knowit-Experience-MarTech/ga4-documentation-administration-solution/blob/main/Apps-Script/08_Annotations-GTM.gs
After you have replaced the Apps Script, go to Settings in the Google Sheet. Scroll down to Version, and add 1.11 as the new version.
