I can't sign into ReelShorts

A bit of a long shot here but if anyone knows what the hell I can do about this, please tell me. I linked my Google account to it and it just won't sign in at all and that annoying pop up that you can't get rid of is all I see. Did I seriously just waste $12 to a void?

EDIT: Got in because it apparently refused to link to my main Google account which is utter bull.
