The estimate process has some new issues. I'm seeing the estimate becoming unstable with having to exit and come back in to get stability back. If I drag an item on the estimate line location, it's about guaranteed to lock out any new activity.
Thanks for bringing this to our attention! This seems to be a technical issue and needs to be investigated and tested on some fresh examples. If the issue still persists, I would recommend you reach out to the technical support team as they are best at technical troubleshooting.
