Hello!
First of all, thank you for Gloomhaven Helper. It has made the game so much better.
We are on the last two scenarios of the game when our iOS users (those of us specifically without a Home button - both iPhone 13s interestingly enough) noticed the same bug in the app's interface. This does not occur on Android, the Mac OS app nor, as I mentioned earlier, at least one phone with a physical Home button.
Se the bottom of the screen for the issue. Notice the details around traps, coin values and the like are gone. In place, there is a vertical column of text. This is the same on both of the phones I mentioned.
Gloomhaven Helper server version: 8.4.12 (Mac, installed via Homebrew)
Gloomhaven Helper iOS app version: 8.4.10
