Monica is garbage. It was said that inviting three users would allow unlimited usage of GPT-3.5, but after using it 40 times in a day, it directly prompts the limit. You have to wait 24 hours to continue using it. I sent feedback and emails to the official asking what's going on, but all I got were automated responses from bots, which didn't solve the problem.
If you advertise that inviting three users allows for unlimited usage of GPT-3.5 for free, then you should practice what you preach. However, the result is the same as for regular users. So, was my invitation in vain? Did I bring in users for nothing?
