I migrated my Fitbit account to Google not considering the effect it would have on my data exports. I had been using the "legacy export" feature to dump out CSVs maybe once a week and copy the new data into a spreadsheet I had setup. When I migrated my account all the data export now goes through Takeout, take it or leave it. 7 years of data is about 2GB uncompressed, 170MB compressed. It will sometimes take days to export, sometimes just an hour and it will tell me there was an error, or occasionally as much as a week. The files are almost always the same (mod new data), but it will almost always appear in my email as 8 archives, then when I go to download them there will be a random number of archives listed on the landing page, between 1 and 5. It's not super crucial, and it's easy enough to digest with a script, but it's wild how janky the process is.
