SolidWorks Student Team Sponsorship Access Issues

Hi there, we have previously been able to access our teams collaborative space directly from SolidWorks through the collaborative designer for SolidWorks app. Recently this has stopped being possible for both long standing and new members and we appear to have had several roles and apps removed from our compass. We can now only install the SolidWorks Add-In app and this only allows access to 3D Drive not collaborative spaces, I can see the files and browse them but not open them and the banner continually says connecting to SolidWorks. Some newer members cannot browse the files either Would someone be able to advise on how to resolve this issue as we rely on this connection to be able to carry out CAD work for the team. Any help greatly appreciated.
