It's my darn document!
If I own the spreadsheet I should be able to edit at anytime, not be "locked out" by others I share my document with
This is outrageous - I can't save and reopen the file to edit even when I have changed and locked the permissions to Read & Write for Myself + Users + EVERYONE....Can't edit ever when I reopen a document. This is STUPID
