How can I apply for a non-O spouse visa in the UK when the online application only shows a tourist visa option?

A user seeking advice on applying for a non-O spouse visa from the London embassy encountered an issue where only the option for a tourist visa was available during the online application process. Community responses suggested trying different web browsers for better functionality and offered reassurance that proving marriage with documentation should ensure a successful application. Additionally, an alternative suggestion was to try the Hull consulate, although it was noted they were closed due to COVID-19.
