I am unable to receive text messages from an Android user who has never been registered with iMessage.
This has happened twice. Both times we were messaging just fine, when I abruptly stopped receiving text messages from her. She has no issues with receiving my messages or sending her messages. Upon testing the next day, the problem would appear to have resolved itself, but the "lost" messages are never received at my end.
I usually use message with iMessage and data, so I do not know if this problem occurs only with her.
Please help!
