Turning on iOS restrictions (Settings - General - Restrictions) and the web filter inside (probably "Websites - Restrict adult content" or something similar in English), I tried whitelisting
wikipedia.org but the whitelist doesn't seem to work. For instance, the page "https://en.m.wikipedia.org/wiki/Role-based_access_control" is still blocked.
I tried whitelisting
*.wikipedia.org/*. It still doesn't work, and I can't find any instructions on how to format the entries.
How do I exclude a specific domain from being filtered?
With respect, please refrain from non-answers such as "just turn off restrictions" or suggesting unrealistic solutions like "you have to enter every possible subdomain by hand without using wildcards".
