Loading error - string did not match expected pattern

Hello there, I’m having issues with one of our surveys loading (Enketo Express for KoboToolbox) - it takes a long time to load then gives the loading error “string did not match expected pattern”.

It’s a very short survey, only 6 simple questions and it works on desktop (using chrome and connected to wifi) but mainly having issues accessing via smartphone (using 4G). Any idea what the issue could be and how it can be resolved?

thanks in advance!
