Ads stop showing up after game has been open for a couple of hours

Speckles the Destroyer of Worlds

I use a multi-timer app to notify me when I can claim any of the ad rewards in this game. Since the recent client upgrade, any time I leave the game open for 2-3 hours, it stops giving me the option to play ads anymore. Once I reboot the app, the ads come back.

I've been seeing others post similar issues in various discord chats, but didn't see a report here yet.
