Locus Map Pro stopped track logging in the background with Android Q on Google Pixel 3 XL

Hi there, I'm using Locus Map Pro on a Google Pixel 3 XL. Track logging in the background worked flawlessly until I upgraded to Android Q where it stopped working (no track log points are recorded while the app is in the background and/or the device is in standby mode). I would like to point out that the Locus Map app is in the "Battery optimization" / "Not optimized" exception list, as is the app "GPS Logger" which continues to log tracks perfectly well in the background with Android Q. I've done several tests with GPS Logger and Locus Map Pro simultaneously logging in the background while the device is in standby. Both apps are in the Android Q batter not optimized exception list. GPS Logger logs well, Locus Map Pro does not log in the background. Using the currently most recent version 3.40.
