A few days ago I updated my BB Classic to the latest version, 2.16.76.2. Since then, I can no longer send videos, any size or to any recipient, I always get the error Media upload error (Error downloading ... server replied: Bad Request). I've uninstalled and reinstalled the app, tried swapping phone (have a second Classic as backup), but no luck. I even contacted whatsapp support, and they replied that the BB platform is no longer supported. Any suggestion? How can I find the previous version (that supposedly it's still working) of the app?
This issue with video sending should now be fixed.
It wasn't a problem with the update, but rather a problem caused by some server-side changes that happened around the same time.
