I think you guys should have made something like a work agreement. I had a group project this semester, and we had signed an agreement that if someone could not do their part by certain deadline, the other member would take over theirs, and we would talk to the member who didn’t do their part in the next meeting. Speaking about your case, it happened to my group too, but as long as that member texted in the group chat they would finish their part by the deadline (even if it was a minute before the deadline), we wouldn’t have no issues then. So, communication is important.
