Inyandikorugero:Navbox visibility
Templates using the classes class=navbox ({{navbox}}) or class=nomobile ({{sidebar}}) are not displayed on the mobile web site of English Wikipedia. Mobile page views account for approximately 63% of all page views (90-day average as of March 2022[update]).
Usage
hinduraPlace this template on templates that directly or indirectly use the navbox attribute, so that editors will know that many readers will not be able to see the template.
Update
hinduraSee https://analytics.wikimedia.org/dashboards/vital-signs/#projects=enwiki/metrics=Pageviews if you want to update the numbers (try smoothing the curve by averaging over the last 90 days).
Numbers can also be updated from pageviews. To update the number, get the (total) value in PageViews on the right (should be in the realm of 20 billion). Then set the Platform on the left for Mobile web (click "Break down by Site"). Get the total. Do the same for Mobile app. Then do the basic addition/division.
Some ad blockers (uBlock origin particularly) will catch the words 'pageview' and 'piwik' in resources loaded to display the graphs. Disable the adblocker for the website in question.
