@nayka Thank you very much for your reply. I am more willing to communicate with you. The QT China team did contact me, but they won't do anything. I can't get any help from them.
In addition, I have a question to ask whether this module can only be used on the mobile phone, because I use EmbeddedAd on the PC to always prompt the session timeout
Now you suggest that I use MobileAd. Is it impossible to use this advertising module on a PC?
