Siri won't read incoming text messages
Most of the time (maybe 8 times out of 10), Siri won't read my new incoming text messages. I'll ask her to read the new text, and she responds "New text message from [name] " Then there's a pause, followed by "you can reply or read it again" But she doesn't read the message itself. This happens whether I'm using a bluetooth headset or not, and whether or not the phone is "unlocked" or not. If the phone is locked, she'll tell me she can't read the text unless I unlock the phone. After I unlock it, she comes back with the "you can reply or read it again" message, without reading the text first. Asking her to read it again just gets me the same pause, and the "you can reply or read it again." But every now and again, she'll read the text message properly. I can't work out anything different I do when she reads the text vs. when she won't read it.
Does anyone else have this issue? Has anyone been able to solve it? Thanks.
