The inbox always shows “no coming letters at this moment” even when there are letters arriving. I have to re-open the app a few times to get the “there are 2 letters arriving..” notification. Also, the red banner “system error” appears quite often. I don’t understand why this app is being featured before these bugs are fixed.For the friends page, it’s difficult to see whose reply is arriving because both incoming and outgoing delivery use the same “triangle” sign. I need to click each friend’s name to check the status of the letters, like whether they have been sent or read or if they have made a reply.For auto-match, even though I opted for matching with users who “last online within 48 hours” , I found that it doesn’t tally with the last online record shown on the profile of the users I matched with.Last but not least, I appreciate your team’s idea in developing this app. It offers a platform for people to make friends in a more traditional way (similar to snail mail but in a modern way) when other similar app or websites are mostly about dating or require instant responses.
