Can't share tracks or track changes on Avid Cloud Session

[BLG]

We just decided to try Avid Cloud again for collaboration after not using it for about 8 months and now it doesn't seem to be working. First I shared the session and my collaborator accepted but didn't see any tracks. Then I remembered that I needed to share the tracks which I did this morning but the upload button never lights up so I have no way of pushing changes to the cloud. I thought this might be because I may have cancelled my cloud subscription, but it shows that I have 100GB free, so I don't think that's it. Is there something else I need to enable to make this work? I even tried changing a track but still no upload button lighting up.

Personal opinion, but Cloud Collab has never been what we all hoped it would be. I would find another way to collaborate. I either send a stripped session with Dropbox(or similar), or share session settings and send a few wave files back and forth.
