Are you changing the "Text Scaling" settings in the "Accessibility and UI" section of the Cromite app, or are you changing the accessibility settinga of your phone using your settings app?
Have you tried turning off and on "Enable Accessibility Service" option in Cromite app?
Have you tried clearing the app data in your phone's app settings and tried reinstalling the app?
If none of these help, you can open a GitHub issue and let the developer know about this.
