I think I successfully installed on iPhone 11 with latest iOS the Libre Office App months ago to open Xls and xlsx documents sent by email but when I (first time, yesterday) tried to click on an email to open the excel file, I do not see any changes in the window that displays the information. It also seems to still be in read only mode. Not sure what app is opening the file but the presentation window looks as before so maybe Apple’s Numbers??? I have retried by opening LO App and afterwards clicking on the email but no changes. Suggestions? TIA, Luis
