Here are some instructions (since you did option 1, try option 3): Reboot and reset instructions for your Tesla - Tesla Info

Maybe check app to see if any updates for it. Or delete app and reinstall and re login with your Tesla account

Do you have good cell coverage where you park? Even if you do, the issue you describe happens from time to time. It could be a Tesla server side issue.
It’s been parked in the same spot since I got the car and never had an issue till now. I did notice today and yesterday that it’s only getting 3G connection, not LTE.

If you use AT&T wireless for your phone, are you seeing the same 3G issue there?
I have Verizon so not sure. I did have LTE at one point today. Maybe my garage is blocking the signal

2021.4.15
ironically, the app connected and woke up the car in less than 3 seconds just now when I went to check the version
This connection problem happens to a lot of us.
It doesn't matter which software version you're on. I bought my car in dec 2018 and I always had it.
The system is just not reliable.
The only way i found to be able to reliably connect to the car is to leave the sentry mode on, but of course it burns energy.

Same version for me too. Hopefully I get one of the 2021.4.15.xx soon and it fixes it.
Waking up the car from the app requires that the app talk to a Tesla server on the internet, and that server talking to the car. If the car is sleeping, it sends an SMS to it. cellular signal is the important aspect here so the SMS reaches the car.
I've seen people having problems when they were home with very poor wifi signal, e.g. the wifi works but it's very low signal. I believe these people have disconnected their wifi and things have been better since. I don't quite understand since it's suposed to take a SMS to wake the car, but it'S something you can look into.

That's correct, the Tesla server uses cellular (SMS), not WiFi, to contact the car. The car then tries to connect to WiFi to communicate with the server, but will use cellular if WiFi isn't available (except for certain operations). That's why cellular coverage is important.
I don't know for sure, but I assume it's done this way for security, since allowing inbound network connections to the car via WiFi would make it more vulnerable to hacking.
Sentry mode means your car never falls asleep. It doesn't need waking with an SMS, it can be talked to directly via wifi or other. Along with the additional battery drain, which means more money spent in charging and more "cycles" on your battery, you're preventing the BMS from being able to capture good readings. Expect your estimated range to drop quicker as a result. It's just an estimate, don't worry, but expect it.

Update: I got pushed 4.18 last night and the car didn’t sleep all night and hasn’t slept since. Yay!
