AliExpress won't allow me to open most pages in the account section on my iPhone. Instead I get a page telling me to install the app.
While browsing, there are also popups offering the app approximately every third link I click. Some of them are telling me to install the app.
Unless the situation has changed recently, it's not perfectly fine, it is unusable on purpose.
AE website on mobile is terrible, they basically force you to use the app. I exclusively use the website on my PC
