unable to open second pdf without closing the first one

[its92226026]

is someone else is having an issue with adobe reader DC and Acrobate Pro when one pdf file is open and you want to open the second one its not open until closing the first one or it take about a minute or so to open, Its happening with multiple users and some are using just adobe reader DC and some adobe pro , I tried to check for any new update but it saying its updated, any suggestions?

My office is experiencing the same thing with most users of both Reader and Acrobat Pro.
