I used this launcher with Duo 1 for a long time and didn't have these problems once I got the right settings. For one thing, I think there is a foldable setting you need to toggle on if I remember right, so that you get a different customization for each screen size. It does mean you need to set up each customization separately, but once you're done you're done. I made instructions for using Square Home on foldable before and you should know these things: 1) Do not use tablet mode. 2) You might need to set the app launcher animation in behavior and UI to Off, Fast, or Default. Otherwise, if you bring up an app only covering part of the screen it may make the rest of the screen, still showing your desktop, do a very annoying blink on and off. 3) On at least some foldables if you try to customize a tile on the right side of the unfolded sceen, the menu will not appear. If that's the case, you need to move the tile to the left screen (or top screen for sideways view) and customize it over there. Then move it back to where you want on the right screen. You absolutely can resize all your tiles to different custom sizes and location for each screen size separately. You also can customize it differently for when you are in "landscape mode" for both screen sizes. This means you should have 4 unique customizations. I think you just need to get the right options toggled. Also, if you have problems with it not rotating look for the "orientation" setting and switch it to "same as system". This should get your rotation back. Square Home actually has a very cool animation when rotating. Hope this helps. I use total launcher now which is by the same developer. It's insanely cool but takes way more work customizing.
