Why am I getting notices my iCloud is at capacity when I have only used 3.9 GB?

Hey there johnsjjj54,

Thanks so much for using Apple Support Communities.

Sometimes the notifications you see about storage space can refer to your iCloud storage, however sometimes those messages are actually in referencing to the on-device storage built into your iPad. The difference is an important one to make, as that information will help you be sure that you're addressing the correct area of concern to get this resolved. There is a great support article here, which goes over the differences between the two types of storage on your iPad: What's the difference between device storage and iCloud storage? - Apple Support

We would recommend reviewing that article and then double checking your storage on both your iPad and in iCloud, so that you can determine the best path forward.

We hope this information is helpful!

Have a great day.
