Anyone have this problem, know how to fix it, etc?
Make sure that you de-register from every Apple device you own as well. I found de-registering only my phone was not enough. I had to do so on my iPad, iMac and MBP.
Maybe? Not that I am aware of, but I could have missed something. I went to each device and de-registered it and texts worked properly after that.I think you can also contact Apple support for that as well, right?
