Microsoft’s IE browser is on its final version. Version 11 is still getting updates for security patches, but has not had a major upgrade in the last three versions of Windows Desktop. It’s old.
As PI continues development with new technology, we will push the boundaries of this old browser which will not be updated for emerging technology.
Microsoft is now using the Edge browser for its future, and PI will continue to work with Edge for full compatibility. Edge is much closer in technology to other newer browsers, such as Chrome and Firefox.
