Spotlight Cam Plus Constantly Offline / Won’t Load Live View (Other Ring Devices Work Fine) — No Fixes From Support

Hello! Was wondering and hoping that someone here has a fix for this or can tell me what to do next. I have used the Ring Spotlight Cam Plus - Plug-In (2022 release) for about 8 months with no issues. About 2 to 3 months ago, it has had some connectivity issues:- It shows as connected, but it won’t take new snapshots or recordings. And it will not load a Live View either.- Then other times, it shows as offline, later reconnects, shows that it's updating but still won't show snapshots, recordings or Live View, then goes back to being offline. And repeats. Meanwhile, my Doorbell Camera and Pan-Tilt Indoor Camera connect to the same Wi-Fi network with no problem at all. And the Spotlight camera shows to have great signal strength (RSSI ~30 to ~40) when it does show that it's "online". I've also tried troubleshooting with it being next to my router and my Wi-Fi extender. This makes me confident the issue is not my internet or Wi-Fi setup. I have tried to reconnect it to my Wi-Fi, reset the camera, connected it to my mobile hotspot, even tried another Wi-Fi to see if the issue stayed, nothing worked. I have tried contacting Ring for the past 2 months for technical help, and to see that if they can't help that they'll replace or fix it as it's still under warranty. The "fixes" they have suggested is to contact my ISP about a firewall filtering issue (I called, and they confirmed it's not an issue), and another Ring support associate suggested I buy a Ring Chime Pro (I already have a Chime, but they want me to buy a Chime Pro to use as a Wi-Fi Extender). I haven't bought one to see if it will fix my issue (as I doubt it will), as I am now considering getting rid of my Ring devices and switching to another company due to the issues I've had with Ring devices and support. I would be grateful if anyone has any suggestions on how to fix or how to move forward with getting my issue resolved!
