Spotlight camera won't record (black screen) and can't go live. Why?

My spotlight camera will not properly save video recordings. Every recording is a 30 second black screen. I also can't go live. I have read the other posts here and have tried everything. Reset my router and reset my device. This week I bought a $270 wifi mesh system to bring an access point closer to the camera. There is now a router closer to the camera than it is to my doorbell. Yet I am having no issues with the doorbell. My signal strength is consistently between RSSI - 47 and RSSI - 51. I consistently get upload and download speeds well above 2 Mbps (upload is around 8). This makes no sense. What is wrong and what do I do?
