I apologize as this post is really similar to another one in 2019, but I did not find a solution there, as the problem seemed to be solved at the time.
Every time I change the layout on my form to “grid” (since I have several matrix question), it automatically comes back to the default form in single page layout.
Would you have any information on this subject to help me?
Did you change the layout setting to grid-theme as outlined in the support article Using Alternative Enketo Web Form Styles? Note: You will also need to SAVE the changes you made.
@fanie, deploy your survey project with the matrix question and then try filling a sample form through the web form. If you see the grid-theme display, then that should solve your issue. It should be an issue if you still do not see the grid-theme display when collecting data.
That is where the bug is, I can see the matric questions when answering on the deployed form, but the related data (the data answered in the matrix questions) is not included when I download the results in an xls form. So I can not use it nor see it.
