Mandatory Offline Data Update Prompt
The feature in question is the "Offline Data Update Interval" setting, which prompts users to update their offline data after a specified time interval. While this functionality is beneficial in maintaining up-to-date data, we observed that users have the option to dismiss the update prompt by clicking "No" and proceed with launching the flow without refreshing their offline data.
We have tested this behavior in the Windows 10 Flow Client, where we configured the offline data update interval to 1 hour. As expected, we received the "Offline Data Expired" notification when the interval elapsed. However, we found that clicking "No" on the prompt still allowed users to launch the flow, leading to potential inconsistencies in data between the offline and online environments.

if you can allow workflow to manipulate data in the offline data set it will be very useful.
