Possible duplicates: Keep both or Merge

1. Open Money → Check your books → Possible duplicates.
2. Look at each pair: date, amount and description.
3. If they are the same payment counted twice, tap Merge. One stays, notes and receipts are copied over, and the other leaves your totals.
4. If they are two real payments (for example two coffees on the same day), tap Keep both. That pair stops being shown.
5. Tapped the wrong one? Tap Undo.

Halves of a split, such as "(split 1/2)" and "(split 2/2)", are not listed as duplicates.
