hello,

answer: now it would take me a lifetime to do this problem for you but what i can do is guide you, first you will need to create your own sketch of the following items they have selected.

glitch or non-saved account.

explanation:

i'm not personally a mobile user but one reason could be that it is either a glitch where it doesn't automatically log you in, or you have it so cant save your log-in information. i suggest you use the mobile app instead of using your web browser!
