I already been blocked by Facebook for I dont know what reason. They than asked me to submit my CLEAR FACE PHOTO for verification. However, when i upload my photo and clicked submit button, the error pop ups ( Upload failed. Please make sure you have a stable network connection and try again later). Ive been trying for 24hours using several device and several network coverage and the results still the same. I have used apps and web also the same error.
Here's how you'd be able to upload past that error:
1. Make sure your browser displays images.
2.b If you cannot use an updated browser, use a browser that can edit your User-agent then set to Desktop display. Then follow the rest of the instructions (select image, wait to be displayed, before clicking UPLOAD).
Note that either way, you must use Desktop view / Desktop user-agent as much as possible.
