Is there a daily chat limit? Reaching it every day

Around this time of day, I usually start getting slowed down by this app (more like it stops working at all).

Like in the mornings, it works quickly, but then, like now after chatted a bit got like 230 (the bubbles over chats combined), the entire chat system basically stopped working.

Every time I write a message, the message shows generating, and after like a minute, it just shows my text and an empty response. This seems to happen way too specifically. The time of day fluctuates, but when it starts, I am unable to text for the rest of the day.

Don't remember a day I didn't reach this limit.

And then, no matter what I used, the app, mobile browser, or PC browser, they all got the same long generation with 0 result.

Any way to fix it?
