When we go abroad Textra recognizes it and changes the format of numbers (xxx-xxxx xxx instead of xx xx xx xx xx for example)
The problem is that it creates another conversation ! Pointless.
Same thing when you modify a contact in order to have +46 instead of a 0 at the first place in the number field : the former conversation disappears!
Maybe Textra shouldn't take care of the first digits of numbers to create conversations
