ChatGPT Plus Usage Limit Reached After Only 30 Minutes

I have been using ChatGPT Plus through the iOS app for a long time, but for approximately the past 30 days, I have been unable to use the app efficiently. Despite having an active Plus subscription, I repeatedly receive a “usage limit reached” message after only about 30 minutes of use, and this warning appears approximately three times a day. Even though I have sent only a limited number of messages within a very short period, I feel excessively restricted for a Plus subscriber.

The warning does not disappear until the time shown on the screen, and I cannot use the app again before that period expires. Closing and reopening the app or signing in again does not resolve the issue. I currently have an active ChatGPT Plus subscription and make regular monthly payments, but the service I am receiving does not seem to correspond to what I am paying for.

I request that the usage limits associated with my ChatGPT Plus subscription be reviewed and that any technical issue or account-specific restriction, if one exists, be identified and corrected. I also request uninterrupted access to the service in accordance with the Plus plan. In addition, I ask that the limited access I have experienced during this period be reviewed and that an appropriate remedy be provided for the inconvenience and loss of service.
