Editing sheets on the go?

Why can I edit sheets on my iPhone and not on my iPad? I checked to make sure the premium purchase was complete in the settings on both devices. I can edit sheets without problem on my iPhone, but I cannot find an Edit button on my iPad.

Thanks for the report! I have filed an issue and we will investigate this. Thanks for your patience and understanding.

I can verify the same issue. I was able to edit the sheet and then it just shut down on my iPad. Now, I cannot edit the sheet.
