I have an Apple household.   Multiple Appsle Products including iPads and iPhone, and 3 x Apple TV' 4's .  I have run with a Eero mesh for well, since Eero started and started having these issues about a year ago.  Currently I am lucky to be able to watch 30 mins of a program (on lowest video settings) before it drops.  It generally drops out at least 6 time in a 45 min program and sometimes drops every 5 minutes.  My iPhone and iPad similarly drop the connection constantly.  My Mac doesn't seem to have a problem (at least not at the moment).  My problems really began upgrading to Eero Pro  - that was a bad move. I've tried all the fixes here and nothing works so have come to the conclusion that others have here.  Eero is an expensive piece of junk if you have Apple products.   Apple and Amazon seem unable to play in the sandpit nicely so I am going to have to right of $$'s of dollars and bite the bullet and buy new mesh wifi.  Very disappointed in both Apply and Eero that they continue to ignore this issue.  

No doesn't disconnect but I get buffering every so often sometimes two to three times but most likely a engineer who doesn't realize that his actions are interrupting someone's viewing pleasure and should wait till the viewer is having his lunch or has gone out.

I can confirm there is a problem with iPad causing the issue. 
I have 

iPhone 12 Pro max

ipad pro

3 eero pro 6 mesh network in 3500sq ft home

i constantly have to reenter my WiFi password on my iPhone. Happened when I leave my house and come home. Will not automatically connect. This only happens if my iPad is turned on, sitting in my house. When I turn off my iPad. No problems. Phone connects automatically every time I walk in my house.
I will keep the iPad off for weeks at a time and there is not one single issue. Once I turn on my iPad. The problem starts again and lasts as long as I have my iPad on. Turn it off. The problem goes away. 
unless you have an exact fix right now, please don’t ask me to jump through hoops of doing different connections in disconnections and turning on things, and turning off things that apparently isn’t working with everybody else, and I followed the entire thread and done all the suggestions and everybody’s responses without success, so maybe the best answer to give us is “we will talk to our support team and communicate with Apple and figure something out “come on

sorry just very frustrated. 

I have this same problem with devices from multiple manufacturers.  Eero support offered no solution.  In fact, the tech said something about my internet speed, which is completely unrelated to devices falling off the network.  Software time-outs prevent things like Sonos from indexing a NAS drive, my printer being accessible, and my Dropcams from being accessed.  It's unbelievable; using v6.15.2-99 with Eero 6+.  Absolute garbage.
