Skype for Business App behaving wiredly after iOS 14 update

After iOS 14 update the skype for business app has has a weird behavior. When in a conference call some of the buttons won't correctly show up on the screen. Also when in a call or conference you lock the screen, the Skype buttons don't show up, it shows a control widget similar to the one that controls

music (pictures attached). Any thoughts on getting this fixed?
