Hi @rabel_6974,
I checked with the product team, and they confirmed that bleed settings are currently not included in any of the export workflows from InDesign to Adobe Express, so this is expected behavior at the moment.
Would you mind creating a UserVoice for this feature request on Adobe InDesign: Feature Requests? Adding your comments there will help us prioritize the request based on community interest, and you'll also be notified of any updates.
It would be great if you could share the UserVoice link here in this thread as well so other community members can upvote it.
Feel free to reach out if you have more questions or need assistance, we're happy to help!
