Yes! I imported 23k media files into a new platform, and the takeout process was such a pain. My destination was built to handle the zipped or unzipped media, but occasionally issues cropped up,like when files spanned archives but the json was on the previous one. That resulted in orphaned files with upload dates instead of date taken.
Ultimately, I think I had the best experience extracting all 123GB and uploading the albums/folders that way.
Would have been SO much easier with an API that allowed cloud to cloud.
