Trouble connecting to M3 on Tesla app

Software v.9 solved that problem for me.
However, I've had to reboot my car twice in the last month (including last night) because it wouldn't connect to my home WiFi and allow me to download the latest update.

I have trouble at home on WiFi. If I’m in my house I can’t connect but when out on LTE no problems. It’s been this way since I got it. Also same with my MS. My house is a cell signal dead spot but I’ve not figured out why on WiFi I can’t connect either, it will only connect when not in deep sleep.

since the .50 upgrade series, connecting to my car at home mostly does NOT work anymore ;(
I'm thinking that their servers are still overloaded. I don't know the exact details of the data exchange, but I assume that when I try to connect to my car, it first goes out either wifi or lte (on my phone), then to a public server that tesla manages, then THAT is what sends an sms to wake up the car. the sms sending services are notoriously unreliable and there's not even a way to get a confirmed ACK back from the sms sender. so that's one area that is weak, in the whole wake-up system. the other is that if we can't even get to the tesla public server (and get any timeslices on its cpu) then our cars won't respond to wake-ups.
not sure its the .50 or their servers but remote connections to the car is very unreliable, now.

the other possible explanation is that the car is ignoring the incoming sms's due to being in TOO deep a sleep.

I'm seeing enough 'bars' on the lte antenna icon, so I don't think that's the problem. some mornings, I notice that lte is 'down' but it eventually restarts itself (likely a watchdog process keeps it going, which is actually quite common in the industry).

My phone (iPhone XS Max) used to always open Tesla, anytime (not a deep sleep issue). Now it never does (started about Sep); I must launch the app first, then car will open. I’m a nerd so it’s not something trivial like Bluetooth off, but I sure can’t find the problem. Wife’s identical phone always works - doesn’t have to launch app.

Enabling the app to run in the background on your phone should solve the problem.
