Two accounts issue!

Hi guys. I use two episode accounts. One is my own account and another one is an account my friend and I made for writing a collab story. When I logged in thru my collab account and then logged out, my personal account showed the stories favourite read thru my collab account. And when I click on a story, it says “story progress missing “ … both my friend’s phone and my phone is Android. I tried uninstalling the app, logging out and logging in, setting up my whole account in my phone all over again.
My avatar profile still shows my avatar.
I sent a report to Episode but there’s no reply. Please tell me if you know how to fix this issue…
