First-time IROS submitter here. I'm curious about the typical review timeline. Has anyone already received papers to review, or is it still early?

With other conferences I've submitted to, assignments usually came in pretty quickly after the submission deadline. IROS seems to work on a longer timeline (notification isn't until June 16), so I'm wondering if the reviewer assignments follow a similarly delayed schedule.

Would love to hear from more experienced IROS authors/reviewers: is it normal to not hear anything on the reviewer side until May?
