Not Optimized Battery Setting Not Being Respected

[belanger]

I'm running 8.1 on my Google Pixel XL and ever since the 8.0 upgrade, I've noticed that the setting that lets one disable the warning about a certain app, in my case Should I Answer?, no longer works and there's a constant Notification that the app is using battery. Anyone aware of how to fix this or do I have to wait for Google?

Thanks,
MB
