If you have "Sliding PaneS (Andy’s Mode) active in the Vault and you open it in iOS (synced across devices via iCloud), the width of every page is weird in portrait mode.
Also in landscape mode the sliding menus (both right and left) are not working properly (they only work if you slide from inside the screen, not in the limits as they do in portrait mode):
Thank you for the report. Issues for plugins and css themes should be sent directly to the author’s GitHub issues section.
I understand that Sliding Panes is a popular plugin, but as a small team, we have to prioritize issues with the core app. Someone from the community should be able to help you out on Sliding Pane’s Github.
