whenever I use my mobile data and no matter how many times I click download even alternate download mode refreshes it shows nothing like before and after clicking the link is the same thing for me now. This problem doesn't arise when using wifi (download starts on one click) and when I am using an external link to download. 

Also just to mention this problem doesn't come when I am using a pc and connected to that same data hotspot. This problem just started out of nowhere and I am unable to find any solution so please help me. Thank you.
