I was not able to reproduce such an issue on our side and we haven't seen such a report after the hotfix release. However, an AppBuilder upgrade doesn't clear the device simulator cache on your machine and there might be something incorrectly saved in it. Can you therefore please clear the content of the cache - it should be available under the %localappdata%\Telerik\BlackDragon\Cache
If this doesn't help can you please send us the logs of the AppBuilder
extension for VisualStudio
. They are saved in the %localappdata%\Telerik\BlackDragon\Logs folder.
If they don't cintain any errors or exceptions, we would also need to have a look at your project and test its behavior locally.
Thank you in advance for your cooperation.
