Looking at all your questions I will try to describe my experience and findings with the Mitsu WIFI AP.
1. my findings are related to a 2022 PHEV.
2 I use a Canadian model in Canada.
3. I use Android, Apple may be a bit different.
4. The WIFI range of the PHEV WIFI is very limited. I don't get more than 20m.
5. I do not get why a car manufacturer put so less effort in an AP. to keep it maintained.
OK here the points:
Depending on the model you own, you only can use one out of the three available aps related to the model year. Wrong year, wrong ap, nothing works!
So first you need to figure out which is the correct one.
One main point for the 2022 model is, that the line changed to the new trim only for the combustion engines in 2022. The PHEV 2022 is still the 2021 trim and AP! It changed in 2023 to the new trim.
But with the car manual and documentation, you received a little card with the SSID and password. On that one is a QR code, that brings you to the correct version of the AP. in the play-store.
In the V2 AP. is a demo as well, you should check if the features of the AP make sense for you otherwise just don't bother.
But if you decide to use it, START FRESH!
Reset the amount of registration on the car WIFI.
I found this in the internet.
DO IT.
Start fresh and clear everything.
It worked for me and it still works.

WiFi Reset Procedure:
1. Get in the car and Fully close the Drivers door.
2. IMPORTANT - All steps below must be performed within a total of 30 seconds.
3. Without pressing the brake pedal, press the power button once so that it glows orange (ACC mode).
4. Turn on the Hazard lights.
5. Now quickly alternately press and release the LOCK and UNLOCK buttons on the key fob 5 times, i.e. 10 presses in total. This must be done within 10 seconds of pressing the Power button ON as in (1) above.
6. Listen for one BEEP, followed by 0, 1 or 2 more beeps.
7. Now quickly alternately press the LOCK and UNLOCK buttons on the key fob another 10 times each within 10 seconds, i.e. another 20 presses.
8. Listen for one BEEP, followed by 0 more beeps.
If you only hear a single BEEP, with no following BEEPs, you have successfully reset the WiFi. You can now register 2 new phones with the car again, using the standard procedure (but see Note below). If you hear more BEEPs after the first long BEEP, then its not worked and you should try again following the procedure correctly step by step and within the timings stated.
Switch off the Power button and Hazard lights.
Note: If you reset the WiFi, before you attempt to connect your phone to the car again, you should first remove the Mitsubishi APP from your phone completely.
Once the APP is removed you can then connect your phone with the car WiFi first and only then, after successfully connecting your phone (not the APP) to the car WiFi, should you download and install the APP again. Then of course you must go through the APP procedure.”
Thanks for that from the source I don't find anymore.
Hope that clarifies and helps you
