I am unable to add notes and am getting the message "Insufficient memory space: 196 MB out of 9.72 GB available". The message was first coming up when I tried to add a note but I'm now getting it when I try to edit my existing notes, which I am also unable to do now. I am using the EN app on an Android phone. My premium account just reset it's usage total yesterday. I have approximately 6500 notes in about 25 notebooks. I've never had any issues until now.
