App lags, saw a 2018 review facing same problem & it's already 2022. A case of refund, to my surprise they sided with seller in china. Why would they lose customers? Some sellers sell knock off products, claim original & God helps us let ip owners do something about this. Chatting with seller but getting reminder to speak properly, tell your sellers to use english instead of chinese! Advertisements in english but can't use english??? In FAQ, they should encourage buyers file reports to TTPM.
