I bought some items that never arrived. The app kept preventing me from making any disputes because its kept saying seller had shipped the items which was a lie. Finally discovered seller had closed their shop and there was no way for me to reach out to them. I never got my money nor a refund and Aliexpress closed the issue without helping me. I'm never shopping from Aliexpress again. Things used to be a lot better and simpler with the app a couple of years ago, now I don't know what's going on
