Issues with ChatGPT 4.0 and way of cuminacting with it /

Hello Team

I am wondering, why starting yesterday, I experience difficulties with the chatgpt communication

Does not follow conversation
Missing major parts elements of the discussion
Does operate with older information

It does not follow the conversation as it was yesterday. Today it is like I am speaking with another person, behind /although it is a machine/

Please advice , because I am a plus user and use this tool as analysis for personal needs.

Also , Do we have limitations of ny kind and if so pelase explain

How types /as words or sentences/ can I send to it daily and how many images it can generate /

And if it is a limitation/ if there is such/ is it supposed to change the way it is communicating with me as user .

Greetings

Lazar
