So this is a weird problem that I haven't found any solutions for. I can't send reply texts to at least three of my contacts. Whenever I reply, the message just hangs on the "sending..." and never gets sent. Most of my contacts don't have this problem. The weirder part is that if I forward that same message to any of those contacts, it sends like normal. Also, if I create a new message to that contact it also sends normally. Any ideas?
