So I am trying to build a custom gpt, its really hard to get it done properly because you have to constantly go back and forth with instructions its a lot of trials and errors, and now after 1 hour of prompting I get this message literally blocking me from completing the creation of a agent. This is big road block since I am trying to create a functional agent… What was the point of subscribing to plus if we so limited? I thought by subscribing to plus I would have the freedom to test freely but this restriction is not what I thought I would face and it literally kills productivity. 
Yes, it’s irritating - thus you need to learn/improve stacking your questions/modifications and not use one prompt for one short sentence
Note; The limit is clearly stated - no surprise there as such
