Live stream not working

I have read other issues regarding this. We never had any issues until we got new internet, which gives us better service than our prior provider. RSSI-58, I have a chime pro. Our speed test is in the 100’s. Restarted router. Removed app and reinstalled. Even completely deleted the security camera and chime and added it back. It either won’t load or will just be a black screen when you try to look at a previous live stream. Extremely frustrating since I pay for this service and the cameras were not cheap!
