Chime Pro unable to connect to TP Link router

My chime pro 2 worked fined for 10 months or so, and then 2 weeks ago it disconnected from the router, despite no network changes by me. I tried resetting etc but that didn't work, so ring support sent out a replacement, which had the same issue. The whole time all my other devices including my ring doorbell worked fine. Speaking again to support they said it was a known new issue with Chimes being unable to connect to TP Link routers and it would be fixed within a few days. Are there any updates on this, as 2 weeks later it still won't connect. Currently stuck with a £50 chime that for 3 months only sometimes rang, and now won't connect at all! Why do ring keep breaking these things?? I don't want to have to keep my phone on me and unsilenced just to be able to hear the doorbell ring!
