Hello, following the connection of my Android to PC using hotspot for file transfers, the permission code of the xender (192.168.20) displayed for me to accept is different from that of PC Firefox browser (192.168.1.111) therefore, when i clicked "accept" from Android then the xender failed to connect to the browser as it showed me a blank page without any error message. Pls how do I fixed it?
