I have a weird UI in the latest version of the app. See the actions menu at the bottom of the screenshot. It does it when I select a series or grouping, it hides behind the OS buttons. I am on a Pixel 8 Pro running Beta (included screen shot of OS too). Hope this makes sense
You found a bug. This is a new bug introduced during our “edge to edge” update last week.
This update was only for Android 15 and higher: it enables more screen space. However, we forgot 2 or 3 screens, and the “select series” is one of them. Will be fixed in the next version.
Workaround for now is to go into phone settings and under navigation, switch to Gesture Navigation. That is a workaround of course, the fix will be going out this week.
Awesome. If you need anything from my setup, please let me know. Glad to help how I can.

No worries, we’ve actually already fixed it, it’s ready to be submitted. Probably later this week 
thank you!
