After the update the game won't sync up with the cloud and i've lost literally everything. Anyone know a fix?

Not sure if this is just me, or if I have to make an account or something, but I have a bug where under weekly challenge it says "Network and online account required.". Multiplayer says online. I feel like I'm probably just missing something but if someone could tell me what it is I'll be thankful....

im subscribed to several custom levels, and i can view them on the game downloads page, but nothing shows up in game when i click on custom levels? tried closing and relaunching several times and also tried to re-download levels and nothing

I have this game on epic games launcher but the multiplayer is weak. There is rarely people on. I would assume on steam it would be more populated. How is the multiplayer on steam ?

I just need attention. thank you kindly.
