I have a libreoffice calc app, developed on windows 10, that operates a ladder league for bowls players. It has 3 sheets, 2 of which are derived from data in the first sheet. Works fine. I have moved the app to Dropbox and created a "view only" link in Dropbox. This link I have used in our wordpress website. Open our website on windows 10 and click the link and our league ladder displays correctly showing the league table and 3 separate sheet tabs. Try the same thing on an android and surprise, surprise it works fine. Try it on an iPhone and the first sheet displays just fine but sheet 2 and sheet 3 are NOT shown. Is there some tweak for the iPhone to get at sheets 2 and 3? Note: There is no extra software on the client computers only their browser. The whole system must work like this I don't want any special software for the iPhone.
