Not sure what category to put this in, but here goes. I simply want to use the app on my iPad to block a couple of numbers from calling my cell number. I've done this many times before, but it isn't working now. This is the feature that should let me block up to 5 numbers (for 3 months). Keeps telling me to try again later. It even shows a previously blocked number with a "Block again" button, but that doesn't work either. Any idea what's going on here?
