Their AI determines what they think is sending spam on your part (mainly because I sent inquiries to overseas agencies asking about rental car policies) and then blocks you multiple times until they ban you and you have to ask for an account review. Don't bother contacting them to ask why: they respond with an AI generated message that repeats over and over again the reasons for the restriction, which tells you nothing other than, "hmmm ... it looks like you may be sending spam". In other words, their AI 'customer service' is as good as their reasoning for banning you.

Sorry, no. First, they assume a knowledge you may not have when first starting out, even at the beginner level. Secondly, AI is not very good at understanding what's being said and will "correct" your statement to what it THINKS you wanted to say. That's no help. And finally, there have been glitches in their responses, such as mispronunciation and freezing on, for example, words which have accent marks that lengthen a vowel. My personal favorite? When I said something and they printed it out in Chinese characters. Finally, the screen display on Apple's IPad is way too small. Not worth it, as far as I can see.
