Touch becomes unresponsive after re-enabling using shortcut

Using Fenix 8 51mm AMOLED. 

I have the Start (top right) + Up (middle left) buttons as a shortcut to enable/disable touch input. Before hopping in the shower, I use this shortcut to disable touch to prevent water from registering false input on the watch. After the shower, I use the eject water function to remove any excess water from the speaker. Will do this 2-3 times even. 

If I do not re-enable touch right away and forget about it for a while, then try to use the shortcut to enable touch later, it APPEARS to re-enable as indicated by the animations and icons in the menu, but touch input doesn’t actually register on the watch. No amount of enabling/disabling using the shortcut or menu or controls will have an impact. The toggles/icons change to indicate it SHOULD work, but ultimately I have to restart the watch to make touch input work again.
