Fresco not syncing, unable to export psd and 'not enough storage'

Hello! I'm having a problem with Adobe Fresco. The last file it synced was 2 months ago, and one of my drawings is still half-saved. I thought the problem was with the creative cloud app on my mac but it hasn't synced to my cloud at all, I checked by logging in online. Today I made a new drawing and it doesn't upload to the cloud, and I can't export the psd, and also Fresco keeps telling me that there isn't enough storage on my phone even though I've used less than half. Could you please help?
