Question regarding hints

[SillyBilly14]

Hello, it has been years since I have played the game and maybe there is more going on, but I recall the game giving you frequent messages if your entry fee is lower than what people are willing to pay, in open rct2 i have yet to receive such message. Are they still enabled, if yes, what are the requirements now? If not, why was it removed? I often am deep in the red so I was hoping for a way to know when or if I should have my park's visitors pay more at the entry gate so they are paying what they deem a worthy prize, and I can keep my park running well.
