I am having the same issue on a couple different Nexus 10 tablets.
I try to sign in to the Buzzsaw app, but the project does not load. I see the 'downloaded files' button, but no project to download the files from!
I am able to log in successfully to the iPhone and iPad app, the app for my Samsung Galaxy S2 phone, the website, and the windows client - all of which can see the project without issue.
I need to be able to use this on these Nexus tablets, help please!
