I would assume that all the data would transfer from one phone to another, like every other app, but no!! Never got a data loss warning on s24 (data has been there for 12 mths without loss), only when i got the s25 (in the last couple of weeks). Why doesn't the data transfer between phones? You want to avoid cases of data loss, I have lost every bit of evidence I have relating to DV, so maybe a warning that if you change phones, no data comes with you. I would never have used this app if I knew it wouldn't transfer over. Thank you for your constructive help!!
