I can’t restore chatgpt on mobile because I bought it on PC platform. In normal mode, GPT works on the same platform. When trying to operate in voice mode, it says that this function is not available. Although I have a full subscription to GPT 4o. I performed all possible actions, including deleting the GPT from the mobile platform and reinstalling it. Nothing helps. You should really start considering the option of abandoning OpenAI if you cannot solve such primitive problems. I only use GPT 4o. And well. On my mobile device it tells me the following. If I have purchased a subscription on the Windows platform, I cannot renew it on a mobile device! There is no answer to my question in any OpenAI forums, I checked.!!!
