Hi @jakecook,
Regarding your first query:
For this, simply try using a tablet with a larger screen (as Enketo ideally is meant for collecting data in a large screen). If you don’t have a larger screen tablet try viewing your survey form in a landscape view. This should also solve your issue.
Regarding your second query:
Would you mind having a look at the post that has been discussed earlier which should solve your issue on adding a skip logic to a matrix question:
Have a great day!
