Alliance screens have a couple of functional issues:
Chat scroll - this can become problematic if there are a lot of DNA requests. Instead of scrolling smoothly, it will miss large chunks of text out and leap back and forth.
Chat messages - sometimes after an activity, such as a battle or friendly challenge, you are unable to post a chat message unless you restart the app.
DNA requests - some do not disappear when fulfilled or collected and an error just appears saying ‘Sorry this action cannot be completed.’
What type of device are you using:
Using a Samsung Galaxy S8+ - latest updates.
