When sharing a phone # in pm's I have noticed that they disappear somehow on my end but when the sender looks in his sent pm box, the phone number still appears. Am I losing my mind? After expirimenting, I discovered that a pm will erase a number separated by dashes for me but not if I just mash the numbers together. Ex. 507-555-5555 will be erased but 5075555555 will not. Aid?
