Hello Chris,
I'm not aware of any limit for bulk recording download requests. You should be able to re-run the same using the Recording Bulk Actions API (for example POST /api/v2/recording/bulkrequests). I think the download URL expires after a short amount of time (60 minutes I think) so if it does expire, you'll need to re-run the API request.
In case you have any further questions, I have moved your question to the Genesys Cloud - Developer Community. Hopefully one of the experts there will be able to assist you with this.
