New features introduced in Chrome 83, break PPM code for Auto-Complete popups. All PPM versions are impacted. PPM R&D is working on the issue and soon details can be found at link QCCR1L69069. In the interim please either do not automatically take the Chrome update or use PPM with a different browser (Firefox/IE11). You can also try and downgrade Chrome if you are impacted by this issue, until a solution is in place.
