My iPhone keeps asking to use my location

I have weather widgets on my Lock Screen and Home Screen. Every few hours they show “—“ or “Location Access Needed”. When that happens I click “Allow while using App” in the popup and then when I return to the Home Screen I click Allow on the popup that says “Allow widgets from weather to use your location”. This works for a few hours and then starts all over again.

If I go into Settings and set the Weather app to “Always allow” it still reverts after a little while. No matter what I do, I have to go through this multiple times per day.
