Hey there Luke, not sure if you fixed your problem. However as I do not know of an actual way to fix this problem I have a couple ideas that will probably work for you!!
First option: You should consider linking other services to your runescape account. EX. Google, Amazon Prime, Facebook ETC!!! This will give you different login options and may bypass your issue temporarily until the bug is fixed.
Second option: I dont know if you've always had this problem or if it just started happening. However sometimes simple problems have simple solutions.........Go into setting on your phone. Go into your "Apps" section. Find the Runescape App. You will now see a few options to view. Click on the storage option. The next page will have 2 options. Clear data and clear cache.
Clear cache: is a sorta data the game collects and downloads after a playing a while and interacting with different things. Try this option first and give it a shot.
Clear data: Since you aren't able to get in anyways I would go ahead and use this option along with the clear cache option. All this does is removes you're saved login info and things like graphic settings you saved for personal preference!! It does not make you re-download the game. This will most likely be a working option for you. But remember to go ahead and clear the cache also.
Please let me know if this fixes your problem at all so I can confirm it works for any future players !!!
Sincerely, Buttonholes. A neighboring mobile player.
