Chime Pro (2nd Gen) connects to Wi-Fi but "No internet connection"

Hi,Randomly my three Chime Pro's (1st Gen) just stopped working. I tried resetting them. two of them wouldn't even light up. As they were all over a year old I didn't want to waste further time on them. I went out and purchased three of the new (2nd Gen) Chime Pros.I cannot get any of them to work. I have tried all three. I have tried with iOS and Android. The result is always the same. I go through the setup, connect it to my Wi-Fi, it tries to connect for ages, the app times out, and the Chime says, "Connected to your Wi-Fi but no internet connection". And then the light starts to blink red. I have tried more times than I can remember now on three different units. I have tried connecting with both 2.4Ghz and 5Ghz.All my Ring devices were connected to the Chime network so nothing on my property was working. What I have had to do as a temporary measure is reconnect the most crucial cameras back to my Wi-Fi directly, which worked straight away without any issues. I can assure you there is nothing wrong with my Wi-Fi or network. It's rock solid.I spent a long time troubleshooting this yesterday with someone on tech support and as helpful and patient as he was, he wasn't able to get any of them working either and said that second-line support would call me back within 2 hours. They never did.I asked on the phone yesterday if there were any known problems with these new Chimes and was told there were none, but a quick search on Google reveals a ton of people facing the same or similar connection problems with them. I can't believe Ring isn't aware.Please can someone from Ring assist? Thanks
