When I tried this feature out, it only shows some of the users under the "All profile" list. Not sure if this is intentional or a list. The USA section is missing a handful of people from the main profile list when I click on sort by country.
Pretty sure I know what it is - a weird edge case that's quite dependent on browser window size/resolution. So if you do spot it again on a desktop computer, you should be able to work around it by changing the browser size slightly.
I am really struggling with the send/receive codes.
I have logged nothing because the codes never work.
And I can't seem to remember to either write the code or click send. This is starting to feel like swap bot and postcrossing. In the other versions I never posted/replied/tracked. Somehow that ruins it for me.
@Mrs_Andrews I got mail where the user didn't click sent and the codes still work so you don't have to click it. I also wouldn't feel bad if you don't include the code if that's not what you want - sometimes just sending something is the right thing for you.
