I have had this lately along with my family. Send a iMessage and it won't say delivered for 5 minutes up to an hour. Has anyone experienced this lately?
I'm sorry, but I can't understand how that is happening, and can only assume you have a corrupted file, app or setting. If you have a "strong Wi-Fi connection", excellent internet service and are able to send and receive iMessages then you should be able to open and read the messages. Having said that, you may need to restore your device and set it up as new. You can try resetting your 'network settings' as well.I'm having the same issue! I only use my iPad at home with my wifi. We have a great wifi signal. Often I can't get my iMessages to even open, much less show the current messages. I've searched the Internet and can't find a solution!
