If the bar is gone, it may be synced already.
You can go to help, click on debug window, and see what your current number of blocks are, check with a block explorer and see if you are current with them.
There is a little check mark to hover over in the lower right corner of the wallet, that may show the info also.
But thanks for for your post by mentioning the debug window I learned about it
This was a helpful advice.
