iPad claims storage is full but storage is clearly not full
Does anyone know what causes this? I was trying to export a 7 GB archive out of LumaFusion and the process aborted, claiming storage was full. When I jumped into Settings, I briefly had an alert that storage was full, but the alert disappeared almost immediately. In the anttached image you can see that I have almost 300 GB free; surely the 7 GB export does not need this much space.
I bump into this regularly when exporting from LumaFusion. It fixes itself it I reboot the iPad, but what is going on here? Is this a fragmentation thing? Is there something I can be doing to avoid the aborted exports?
