A bug in the Gemini app has led to the removal of several features, including the ability to upload NotebookLM notebooks via the ‘plus’ menu, the disappearance of the “Temporary chat” button, and the option to “Import memory to Gemini” from the profile menu. The app's design has reverted to side-by-side pills from a list format, and the background color has changed from black to gray, affecting the visual experience. Android users have also experienced a return to a previous overlay design that limits access to the Tools menu, and the fullscreen glow effect has been removed. This issue is affecting users across both stable and beta channels with Google app version 17.14, and a server-side fix is expected to restore the lost functionalities. The Gemini web platform remains unaffected.
