Thank you for reaching out. The Feb. 9 update to was an infrastructure-only update that did not affect workspaces directly and should not have had any effect model on performance. We haven't been able to identify differences from before the update and after that affected model operations, but if you continue to experience problems in this area please reach out to Support and we will troubleshoot.
If you would like to get an update on our product roadmap, please arrange it through your CSBP and we can tell you what's coming and what we know about current timelines.
Finally, the team delivering the Beta of the New User Experience team tells me that the snap to grid feature you are talking about should be visible to all Beta users, and they have not received any reports of feature differences. Could this be from browser differences?
