Some general things I am seeing. I might have reported one or two of these before, I'm not sure:
1 - When uploading many projects at once (say 5 or more), it seems to stall out and stop uploading completely. I can see in my task manager, that my Internet is not being used. If I reboot Momento, and start over, it says that my file names are already in use, so I have to give my projects new names. My work-around is to never upload more than 3 projects at once.
2 - If I delete some projects from teh A360 drive in Momento, they go to the trash can. I then empty the trash can, but the "Available Storage" label in the lower left of Momento does not appear to change.
3 - Frequently I will get emails that a project has finished before Momento knows that it has.
4 - Often if I run a project as "best" it fails with an email telling me so. If I run that exact same project as "Draft" it comes out okay.
