Hi @Dreamer-4pda, I assume that the problem will be that my patch is based on KivyMD v0.1.0, while you are trying to run it with KivyMD v1.1.1. At the moment, I cannot tell when I will find time to update the patch, but most probably not in the foreseeable future. I suggest that you compare my patch with the original version that the patch is based on and try to make the same changes in the current v1.1.1. On my part, no extensive changes were needed, so with a bit of luck, you can do this with little effort. If you succeed, a pull request would be very welcome!
