Whenever I make a significant change to my AquaMail configuration, I make a fresh backup. I run the app on my Samsung phone and also on a Samsung tablet; apart from display differences, they share the same configuration. The last backup was made on January 27 of this year, and both phone and tablet produced files of approx. 47KB. Today I have backed up again, but the file sizes this time are not just bigger, they are also puzzlingly different: the phone file is 6.84MB, thtablet file 83.47MB. Is this normal? If so, why?
