After further investigation it appears server connection have been lost with this change.
The car did fully charge overnight, the numbers that appeared in the app were cashed.
The charge schedule is stored in the car. The HondaLink app is just used to remotely set the new schedule within the car. For example if your phone is completely powered off the scheduled charge will still take place.
Your incident that the schedule was lost and the next time you plugged in it immediately started charging, normally that occurs only after a hard reboot (disconnecting the 12V battery for a few minutes which clears all previous settings)
Something has definitely changed with my HondaLink starting a few weeks ago. It still works but it has some weird quirks. Note that the range and SOC is always cached on the Honda server, not on our phones. Launching HondaLink causes it to connect to the Honda server via standard Internet to get the latest info that the Honda server has. However the data on the Honda server is only what the car last reported, which the car does only for a few specific events which is mainly:
Start charging.
End charging.
Charging SOC milestones 25, 40, 55, 70, 85, 100.
Turning off the car.
Plugging in a charge cable (even if you don't start charging).
The car is not plugged in when a scheduled charge time arrives.
Note that unplugging the charge cable will not initiate an updated report to the Honda server, only plugging in does.
When any of the above listed events occurs the car "calls" the Honda server on the cellular network and reports the current status including miles and SOC. The "Last Updated" date and time that you see in HondaLink is the last time one of these events occurred that caused the car to call in with updated information.
Status updates are also received whenever the Honda server "calls" the car, which includes the following situations:
Turning on remote climate.
Start charge remotely.
Schedule a charge or modify an existing schedule (see * below)
What has changed recently for me (sometime in the past few weeks) is that many times when I launch HondaLink it gets stuck on the initial general info screen. Normally the general info screen displays for a just a few seconds and then the charge status appears. Now as often as not it just stays on the general info screen. If I close Honda Link then immediately reopen it, it acts normal and within a few seconds shows charge status. So this is a bug in the app.
And now oftentimes even when it does show the charge status screen there are dashed lines in place of miles and SOC. I have seen this before in the past but very rare, now it happens quite often. Even weirder is sometimes it shows charge status for a few seconds but then blanks it out with dashed lines.
Again this is all information that is already stored on the Honda server, so these quirks are entirely related to the connection between the app and the Honda server. It has nothing to do with the connection between the car and the Honda server. I know this because in the above scenarios when I finally get it to display charge status, the Last Update date and time is still the last normal event that caused the car to update the Honda server. Meaning the information for the car was there on the Honda server but the buggy HondaLink app was having a problem displaying it.
* When I want to get current charge status but I don't want to wait for one the above listed events to occur, I go into Schedule Charge then press Modify, but then I don't change the schedule I just press the check mark. The Honda server then calls the car to update the charge schedule within the car (even though the schedule didn't change) and the charge status in HondaLink then gets updated. All of this takes about 45 seconds. Some people claim that Find My Car will cause the charge status to update, but that has never worked for me. In my experience when you turn off the car, along with charge status the car reports its current location. So no need for HondaLink to call the car to get the location since it already has it from when the car was shut off.
