The shortcut button in the nav bar for accessability features dissappears after a period of time. 

I use the button primarily for Google Reading app. It's really good. You can have multiple apps of your choice for the accessability button. 

Not sure if it is the Google Reading app or a glitch with One UI 7?

Here is a screen shot of what I am referring to. 

The accessability button is the far right little man icon. Yes, I am running Goodlock and Navstar for further customization, but have ruled this out as the issue for accessability button dissapearing as it happened before the Navstar module was available. 

Hoping to find a fix for this. As of now, I have to uninstall and reinstall the Google Reading app and reset all permissions, etc.😔
