If, perchance, you have selected SAVE or hit CTRL+SAVE on your keyboard and proceeded to wait MUCH longer than you would prefer for Adobe Analytics to present you with the dialogue box to actually CLICK the button to SAVE the most recent update you made to your Workspace. Here is a simple workaround:
Instead, simply select Share > Share Project
Then, you can make any additional updates, selections on that screen, and then click the UPDATE button, and voilà, your Workspace project has been SAVED!!!
No more waiting, and no more frustrations.
