@thefuckijustsaw Hi, I'm sorry but I don't have any idea why its happening or how to solve it.
I too faced a similar issue, an year or so back, somehow it got solved after uninstalling a few times, downloading the app from Google instead of play Store (before downloading from such sites, make sure it's free of any viruses though) and just giving it a time.
If the issue is still not getting solved, you maybe try contacting these Wattpad people. You can find the customer care no. or something from Google.
