I have been having real problems trying to do Google takeout with my Google Photos. I keep getting an error emailed to me saying "However, we were unable to create a copy of all your files. You can still download your files until September 25, 2022, but please be aware that there will be data missing."
Apparently I am not the only one[1][2]. Other people have a mix of errors[3]. It is not the reliable data extraction I was expecting for something as valuable as my family photos. Google is losing a lot of trust from me based on this.
