Poor Performance on Mobile

Question

I have a survey created with the web designer.  It is a bit lengthy and does include skip logic.  The survey behaves as expected on desktops.  However, the form responds slowly to scrolling and selections on mobile devices using a browser.  For example, when simply selecting a radio button, it takes up to 3 seconds (e.g. on a galaxy 7 with chrome via 4g or wi-fi) for the radio button to appear as selected. I've tested shorter surveys on mobile devices and have not had this issue, so it appears to be a function of either survey length and/or logic.  Is this a known issue?  Is there a work-around?  Any suggestions appreciated.  Switching to the mobile app is not preferred.

Hi Chris,

The development team has done a lot of work on the new web app which can render surveys both from the web designer and Survey123 Connect, which also will bring a performance improvement for old surveys. The current plan is we will use the new web app in 2.6 release (late Jan. 2018), please stay tuned to our blog.

Note:

* For surveys created in web designer, the owner need to republish the survey in Design page to benefit from the new web app

* For surveys created in Survey123 Connect, the new web app will apply automatically

Chris,

Thanks for the information. Also looking forward to the test survey so that we can try to make it better for you.

We have about 30 questions, most of which are tied to skip rules.  Number of choice items isn't a factor - 2 or 20 behave the same.  I'll send the test survey to you in an email.  Thank you and much appreciated!
