Just to be sure, you are familiar with updating layer combinations in Solo projects ? and you are doing the same with no result in the Teamwork project ? or you are new to this ? it might be a bit confusing if you are not familiar with it.
If you are new, I would suggest the easy way of doing it ... open layers settings, reserve , select the layer you want to update " from the right side of the window" look at the status of that layer in the combinations "the left side" and to update the status of it , just click on the eye/lock icon next to each combination name "the left side" . and that's it . no need to use "update" button. that should do the trick.
If you are familiar but its just the team work issue, I would suggest that you ask every one to release all/send , and from your computer. reload a fresh copy the project from server. you should face no issues.
