The app does not give ‘export as csv file’ option when ‘All’ probes is selected.
Hello,
Sorry it does not have the function to export all probe data together.
If you want to export data, please select the probes individually and export. If you select all probes, it is not possible to export data.
Is this a device limitation? The app can easily query each probe separately and create a unified local csv file.
I have fed it back to the engineers and they will optimize the app in the future
