I have done everything suggested here! Went to the setting page on my gmail account and deleted all the IMAP labels. Selected POP3 for all mail and deselected all the IMAP options. Then went into the phone, and also tablet, and unchecked the 'automatic' tick box, then selected POP3 when given the option. In each case, the screen would change to a login screen for gmail and from there it was all IMAP. I guess I will just give up. I do hate it when computers insist on knowing what you want without giving you the possible options!
