Hi, I have a Trophy LR 2023 too and a Zappi2 charger. I also moved recently to Intelligent Octopus Go from a simpler Octopus tariff.
Since this change I have had exactly the same issue you described, ie: Octopus sets up the charging schedule, l wait patiently until the following morning when l find that only about 0.5kWh of charge was added to the car, after which the 'EV is full' message.
I therefore have to revert to manually setting the Zappi to Fast charge the car, which is a pain if you want to capitalise on the Octopus cheap rate periods.
Have you found a solution to this problem?
UPDATE.
The failure to charge problem appears to have been solved.
The MG 4 was delivered to Frasers of Falkirk on 9 December 2024 and during the remainder of the month, no fault finding feedback was provided to me.
On Monday 6 January 2025 at 11am I visited Frasers of Falkirk and walked into their workshop and asked to speak to the technician who was dealing with my car.
Unknown to me, I was speaking with the Service Manager who declined my request and immediately tried to usher me to the Service Reception.
I was aware that the service reception personnel knew nothing about the technical details of the fault diagnosis.
Fortunately, I quickly realised that the service manager who was indignant and evasive knew what tests had been carried out and I told him that I believed that I had located the fault by using a UK data base.
I explained that the early MG 4 Trophy without the rear windscreen wiper, had a known fault with the CCU which was preventing charging.
The service manager was obviously taken aback and admitted that this was a conclusion which the garage had made and they were waiting approval from MG Technical.
At 2:55pm on the same day, less than 3 hours after my visit to Frasers of Falkirk, I received a phone call from Service Reception to say that MG Technical had approved the replacement of the CCU, the part was located within the UK and would be delivered within 2 days.
On Thursday 9 January 2025, in the morning, I was able to collect the MG 4, having had the CCU replaced and was fully charged.
I had intended to delay this update to ensure that the replacement CCU can cope with the menu of stop/start charging offered by Octopus Go.
Unfortunately, I have only used the car for short journeys and there has been no need to charge.
My advice to anyone with a similar charging problem, is to tell the MG Agent, that this is a known problem and to check out the CCU.
Should there be any other charging problems, I will update this post.
I am very grateful to those of our members who have contributed to this fault finding issue.
It's a pity the MG Dealers don't us "common sense" in asking around!

I have just noticed a post by Arog1354 concerning the charge schedules set by the MG app.
If you are using Octopus Intelligent Go, the charging schedules will be set automatically when you plug the car into your charger.
You MUST ensure that all other schedules, i.e. the car, the charger etc are deactivated although you should set the battery charge level within the iSmart app. I my case I set this at 80%.
If you set charging schedules in any app, it will be in conflict with Octopus Intelligent Go.
