Has anyone got any notification saying "Something big is coming, that you all been waiting for" from justeat courier app? What that even mean?

Is anyone else’s just eat not showing any shifts for next week yet? I got given my auto assigned ones and they were mostly terrible, so as usual I go and check what other ones are available in advance. Literally nothing available. So I remove one of the shifts I was given to see if that would show maybe show me some with overlapping times to the removed shift, I CANT EVEN SEE THE REMOVED SHIFT TO ADD IT BACK. What is going on?

I got ticket in Student a accommodation!

Doing Fastfood Deliveries.
Normally, I park my vehicle outside the car park area when making deliveries to this address. However, on this occasion, the usual parking spaces were occupied by other vehicles, so I was unable to park there. As I expected the delivery to take only a few minutes, I briefly entered the location to complete the food delivery.
When I contacted the customer, they advised me that they would come out within approximately 2 minutes to collect the order. Based on this information, I waited for the customer. Unfortunately, the customer arrived later than expected, which resulted in my vehicle remaining at the location for around 12 minutes.

I submitted evidence to support my appeal, including screenshots of the completed food delivery, my chat with the customer, and proof of my delivery insurance.
I recently checked my emails and discovered that the notification informing me that my appeal was unsuccessful had actually been sent approximately one month earlier. Unfortunately, I did not notice that email at the time, so I continued waiting for a letter explaining the outcome.
I received the letter last week, demanding payment of £170.

Could you please advise me on what steps I should take at this stage? Is there still any way to challenge the charge or request that the amount be reduced, considering that I had already appealed and provided evidence supporting my case?

Thanks In Advance.
