Hi @leobragatti! Android has a limitation of the number of cell types it can use in a single ListView. If you're not reusing your DataTemplates (i.e., you return a new DataTemplate for every list item), you'll run into this limitation quickly. Please make sure you're following the instructions in https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/templates/data-templates/. If you are still unable to proceed, please attach a small project that demonstrates the issue you're having. Thanks!

Thanks for the help @samhouts . I checked my code and I was using the TemplateSelector in a wrong way.
