The issue is you probably have dirty plates.Thanks for answer. No sale. I think they detect me but i dont understand how. It is my new account on pc. I sell 30 hours ago 2 cars. i sell one and second after 1 hour and when i try to sell third i reach sell limit. Today i try to sell 1 by 1 milion and i have now limit after first car. I own game about 2 years i m not big level 40 but i didnt sell any car before suturday and today one. Totally i sell 3 cars in 2 years. I have game generated plates i dont know how to make custom plate. I buy most expensive when i upgrade issi with benny.
The dupe you are using makes cars with identical plates.
That means you are dupe detected and is why you have a sales limit.
You should immediately save over all of those dupes with free cars.
Otherwise you will continue to have a sales limit and possibly will get to a point where you can only sell one car per day forever.
Making a custom plate is easy but you need to have the iFruit app to do so.
At this point you may not be able to make custom plates since it seems that you are dupe detected.
