**Reported bugs**

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

**Requested features**

- Could use some personal connection . As they do once they learn your personality .
- Finding a sales job
- Pero es de pago 🫨😬🫤
