Out of cloud storage space - how do I get more?

What subscription do you have?

You will probably need to discharge pictures from your phone to your computer. This is not witchcraft, there are no other solutions except to delete something.

What takes space on the phone and in the cloud are videos! So if you have many videos, you may run out of space rather easily. It is most likely a good idea and to walk through the videos, to see, what can be deleted.
