Despite the glitch in Gemini 2.5 Flash, users still have alternatives to continue their use of the app.
The previous version, Gemini 2.0 Flash, and the preview version of Gemini 2.5 Pro, both allow file uploads. However, these options come with certain restrictions for free users.
For those who have subscribed to the paid Advanced plan, file uploads are still functional in Gemini 2.5 Flash. In the free version, it’s hopefully just a bug that will be fixed soon.
