I have developed a service website for finding bicycle rental stations, this is my practice work.
But when I encountered a strange situation, I shared this website to my friends on facebook and other social apps. Some friends responded that the map was blank when they opened it, but it was normal to view it on a computer. The computer can see the map normally!
Would you like to know what might be the cause? Thank you for watching my question. If you know the possible reason, please share with me. I will be very grateful for your help, thank you.
