Pulse not sending attachment after upgrade

metabase version: 33.6

when a pulse is sent with a table from metabase, previously it attaches a csv file but now after upgrade it doesn’t, even though when you set up the pulse, it says it’s attached.

Any suggestion

Which version did you upgrade from?
Are you talking about email or Slack?
Does it also happen if you go to a pulse and click “Send email email”?
Does it also happen if you create a new pulse, or does it only happen with old pulses?
What do you see in the log, when pulses are sent? Admin > Troubleshooting > Logs
