Yes, this most definitely has been a problem during August. I have seen that other sellers have had similar issues as well. For me it was 6 large letters. 2 of those eventually turned up. One got returned to sender. Not sure what happened to the others. On the whole Ap does an amazing job, but just lately the missing mail has been giving me a head ache. I had none go missing for more than 6 months, then suddenly 6 complaints inside of a week.
