Mac App Store Updates stuck in "Waiting". Anyone had this issue before?

Hi,

I stumbled upon this issue yesterday where I had a software update waiting for me at the Mac App Store, and when I hit the update button on the store, the update got stuck in the "Waiting" message that appears to the left side of the "UPDATE" button. The updates did not appeared to download nor start, they just got stuck in the "waiting" stage. Moving to the "featured" section of the app store did not worked to re-highlight the UPDATE button in the update section of the Mac App Store page. The only way I was able to solve the issue was by Force Quitting the Mac App Store and trying again. On the second attempt, when I clicked the UPDATE button the "Waiting" message appeared but then disappeared and showed the expected download and install progressbar in the Mac App Store updates.

I was wondering if someone has seen a similar issue to the one I am describing.

Thanks for your time and answers!
