Starting around 7/1 Fit Files downloaded manually from ones www dot zwift dot com/feed no longer have a YYYY-MM-DD-HH-MM-*.fit style filename ex: 2021-06-30-16-01-10.fit.
They now just give you a filename of a hash like 479ca1bd-841778387607427761
So one can rename it, usually at least a .fit needs to be added. So not really a big deal but it’s annoying and I assume some type of unintended bug.
Please take a look thanks
