ChatGPT (GPT-4) unusable due to "Our systems have detected unusual activity from your system. Please try again later."

I’m having the same issue. I’ve not been able to use the service in 2 days. I’m a paying member. If this continues I am switching to Grok 4. How do I resolve this?

In android system just long press on chatgpt icon than choose app information than open storage than look down last of the page you will find small icon ( clear data) press on it and choose clear all data, everything will back to normal but you will lose all your conversation carful for that if you have something important

I have the error while using GPT 4.0 by text, for voice working fine.

ERROR below mentioned: Our systems have detec unusual activity coming from your system. Please try again later.

I have a same error.

Our systems have detected unusual activity from your system. Please try again later.

I don’t do anything unusual. I am not using API key or any extensions. I am a paid user. I don’t understand whats happening. How can i open ticket on openai support?
