Hi @brianzjj thanks for checking in & sharing how this is impacting your team. There was a bug fix for a related issue that went out on v3.36.0, but it sounds like this must be a separate issue.
The return block should ensure the workflow is run synchronously from the app 
Could you share an export of the workflow so that I can investigate further with our team? or, if you can't share an export with us, post screenshots of the return block & app trigger?
I'm not able to set up a 1:1 call, but if we haven't sorted it out by tomorrow, I'd like to take a look in office hours if you're available to join
