So far this year they've discontinued Paper (app), Passwords, Send and Track, Vault and Capture. Incredibly, Vault was discontinued by automatically turning PIN-protected folders into regular unprotected ones! Would be stupid to rely on them for anything other than basic file storage at this point.
Why rely on them at all? Dollar per GB they cost more than literally any other solution with file storage.
I don't know how it is these days, wouldn't be surprised if other commercial services still haven't figured it out.
