I recently had the new BT Hub for Business Broadband. I now seem to have a connection issue with Facebook Messenger with my Iphone XR. Receiving messages if fine over Wi-Fi, but receiving attatchments or trying to send a message etc seems to be on hold until I switch off the Wi-Fi then it receives and sends instantly! I cannot find a solution to this. Network has been forgotten/reset to no avail. Any ideas?
