I had problems installing old apps and I can guide you on how to solve that annoyance Google added in Android 14. If it is something else, you'd better give a more detailed description of your problem.
A lot of apps aren't functioning right since this is still beta. I can't access anything work related because their security doesn't recognize it and some games like FF7 Ever Crisis won't play either. It'll probably resolve whenever they FINALLY release the final version.
Not sure about the LED case. But when using the other screen covering case, with the square hole in the top right. No time, notifications, or media playing displays anymore. I assume it's a beta issue that will be fixed in the stable release. Just give it time! I know it's frustrating.
