I turn off arrows because I find them annoying and because of this I found a copy error which led me to repeat this lesson 4 times before I found out the copy error.
The lesson is: Using APIs and sending data to groups.
In the copy it says “having 1 row and 3 columns”, see the screenshot:
When I select 3 columns, it gives me an error.
The reason is because it wants 4 columns! And you would only know this if you had the arrows turned on, see screenshot:
After my third attempt with arrows off, I only realised the issue after turning arrows off. I hope its not too much effort to correct this issue!
