It does not work

I have to attend classes online every week. It used to work fine earlier but from past semester I am having issues. Every time I will click on the link it will ask me get Adobe connect for mobile and will take me to the App Store where as I have already installed the app. Then I will select- open and it will take me to a the page where u join the meeting or class. But most of the times it says - you meeting has not yet started and will get stuck there. Please rectify this issue.
