Survey opnes/works in webmode but not on tablet

namubiruma · April 17, 2023, 1:11pm

Hi users! Something puzzling is happening with my server and I am not sure how to fix it. I wrote two quite similar surveys in designer, compiled and tested them. I then imported them on the server and created assignments. One works fine, the other one won’t open on the tablets. They both work on web mode instead. What could be going on?

On the tablet, I receive the assignments but when I open them I only se “Overview” and “Complete” (I do not see any of the sections). And soon after I get a message “Unfortunately, interviewer has stopped.”

Thanks

What does the tablet log say?

Sergiy thanks for getting back to me. I am not sure how to access the tablet log. On diagnostic I clicked on “send trace logs” and it says that logs are sent to HQ but cannot find them on the HQ site. What that what I was supposed to do?
Thanks,

Hi Sergiy, I believe I was able to access the logs but I am not sure how to read them properly. I am copying it below in case it is useful / you can understand what is going on.
I assume that because when I activate the web-mode the links associated with them work fine, the problem is not on designer but on the tablets? However I tried with two different tablets already, uninstalled and re installed the app to make sure we have the latest version etc. What else could it be?

Thanks a lot,
Livia

What version do you use on the tablet?
If it’s not the latest, please update server and tablet to the latest one, and try again.

namubiruma · April 18, 2023, 1:58pm

Ok - I was using the one I have on the server, 20.08.2 (build 29147). How do I update the server?

sergiy · April 18, 2023, 3:32pm

One thing you can try rather quickly is try to connect to a demo server by setting up the Interviewer App from there.

If it doesn’t work there may be something peculiar about your devices. Make sure they are not rooted!

namubiruma · April 19, 2023, 10:57am

It was simply the server not updated thanks for the suggestions!

sergiy · April 19, 2023, 2:42pm

Thank you for confirming that the update has solved the problem!
