St.download_button working intermittently on cloud

Hi ! Facing the same issue with generated .xlsx files, i tried to use deferred data loading and direct bytes content, and in local it works 100% of the time, but once deployed it’s unstable. The behaviour is a bit different on my infrastructure : the files seems to be generated with success most of the time (no data corruption) but they are not downloaded, they’re “queued” somewhere.
