A couple of months ago, I shared my ChatGPT Plus account with several people on the condition that they could use it for a couple of days. I did this because my GPT account was the only one among my peers that was not having a problem during the November-December GPT issue, where people had difficulties uploading PDFs to the chat. Recently, I found out that those people who I lent my GPT account to are using it without my knowledge, and it kind of pisses me off since I paid for it, and they are using it again without my consent or acknowledgment. I tried to click the “log out of all devices” button in the security section of my GPT account, and it worked for devices on PC but not for the GPT mobile app. I have enabled multi-factor authentication, but it doesn’t work, and those people keep using it up until now. What should I do?
TL;DR Log out of all devices doesn’t work for ChatGPT mobile (I double-checked it on my phone).
