Video doorbell 3 Plus speed of response

I am getting the same issue with the orginal doorbell. It just doesn’t react quickly enough to going to live, to talk to a person. If it connects, which is rarely, the persona has normally left. It says my wifi to the device is ‘good’ and I have extenders around the home. My wired units connect, but this doesn’t…I think the unit is faulty, but cannot currently find a number to call anyone at the company…it just send me to these forums, which isn’t a solution. Not happy.
