After sales support is awful
After sales support is awful ! I bought an AP80 PRO MAX, which is supposed to support 2To SD-cards ; when I tried with a 1To card, the product was not able to build the songs library and repeatedly crashed ; I tried to contact the support, but they don't seem to feel concerned, no solution nor even an attempt to fix the bug ! In the end, I am able to use the product with smaller cards and less songs, which means that I cannot load all my songs, very disappointing !
