Hi! i have a windows 520 phone and it runs on windows 10. i have instagram (not beta) for quite a while now but recently when i open instagram it just goes onto the starter page (its like a black screen whith an instagram sign in the middle) then it crashes to the home page. i have tried reinstalling, refreshing the app, restarting literally everything you can think of. when i install the app it says that i need 2Gs of storage but i have 3Gs to spare on my phone and 13Gs on my sd card. i dont understand how it worked perfectly before but now doesent work at all. also this happens on twitter and facebook.
The reason might be because the app itself might prefer for you to have a certain amount of memory available in order for it to run. Your phone has 512mb of ram so Instagram is probably struggling for that reason.
