Плохо

Не работает генерация изображений

Response from developer

Благодарим за ваш отзыв. Мы внимательно перепроверили нашу систему генерации изображений - за последние месяцы никаких технических сбоев с нашей стороны не было. Судя по всему, проблема возникает на вашей стороне. Причина может быть любой: от нестабильного интернет-соединения до некорректной работы приложения именно на вашем устройстве. Пожалуйста, напишите нам в службу поддержки - мы с радостью поможем вам решить эту проблему.

Love this app

It has been so helpful with so many things . I have created an adhd assistant and planner, a custody binder, and a court planner. On top of a comic strip for my mother about the funny things that happen at work and a multifaceted plan for a hotel and resort with animatronics massage, parlor cosmetology, clinic game room, T lounge and much more complete with brochure, business cards, photos and schematics as well as a financial rundown for property building supplies and entertainment as well as possible locations to build it both land available for sale and out of business theme park for a possible turnover it can do anything and everything. This guy is the limit.

Благодарим за ваш отзыв. Прежде всего хочу обратить внимание на то, что если ваша подписка отменена, никакие средства с вас списываться не могут ни в коем случае. Как обычно бывает, в ходе нашего детального расследования выясняется, что у пользователей вообще не было никакой подписки. Что касается связи с техподдержкой, приносим извинения за задержки с ответами — иногда к нам поступает много обращений, но мы обрабатываем их так быстро, как только можем. Ответ от нашей техподдержки не может занимать больше 2-х рабочих дней. Пожалуйста, перепроверьте внимательнее ваш почтовый ящик.

Stuck in advertisement hell loop

This morning, I was using my ChatGPT that I already paid for and then some advertisement popped up and now I’m stuck in some loop of advertisement about a new and improved more expensive version of ChatGPT and I can’t get back to using what I’m already paying for enough already

Reported Bugs

3 issues

Takes a long time to load if it can even answer. Waste of time and money.

Bug

The app is really slow and it always answers to where you have to scroll up to start. Also, there is no audio, which is disappointing. And whenever you ask a question, you always have to scroll up on an iPhone 12 to see the box where you type. It's just a little thing, but it's annoying. I was hoping for better and hopefully in time this will be better. Thank you.

Bug

I have only had this version for 5 minutes and it has already asked me for feedback. I just want to try it for three days but see that I am 'subscribed.' So how go I cancel should this version not work out. And, if it is working, how do I find the rules for use? Thank you
