Is there a downgrade description from version 12 to version 11?

We ugraded to version 12 some weeks ago. But most users don't use it anymore, because of missing mail feature.

I tried rolling back the folder /opt/openproject/ except subfolder db, but this did not work.

Yes, if there is no change we will roll back too.

Would be helpful to know how to do it.

How to roll back 12.1.6？Because my container is‘n work；for example:compose_seeder_1、compose_autoheal_1

Hi Thomas, hi Piotr, hi Q LH, 

There is a feature request about immediate email notifications on project level: https://community.openproject.org/projects/openproject/work_packages/40190/activity

I have added a vote for each of you. 

Best regards
Samantha
