What is the first step to take if responses cannot be uploaded from the offline app?

The first step to take if responses cannot be uploaded from the offline app is to update the app to the latest version. This is crucial because software updates often include bug fixes and improvements that can resolve issues users encounter. If the app is outdated, it may not be compatible with the server or might have unresolved technical glitches that prevent successful uploads.

Ensuring that you are using the latest version of the app can also provide the most recent features and enhancements designed to improve the overall functionality. Therefore, when troubleshooting upload issues, starting with an app update is a logical and effective first step, as it often directly addresses common problems associated with older versions.
