Ridiculously slow sync?

Hi, Am I doing something wrong with this camera? I thought I did my due diligence before buying, and chose the best camera for my needs, but I’m on a long sailing trip and everytime I use it, I’m looking at over a week of time just to sync to the cloud to be able to clear storage space for further use. It’s become entirely unusable for me and I can’t believe this is normal? My WiFi connection is good when this is happening.

Thanks for any help. I am getting on in years but I didnt expect the throwback memories of dial up internet speeds 😅😢
