Hi
I am using Collabora on an iPad with an external monitor and mouse.
I am using the developer beta of iPad OS 26
So far, I think the product is awesome by the way !!
Mouse scrolling does not appear to work either on the iPad screen or the external monitor. Touch scrolling (with finger) does. Not too much of an issue with documents because a scroll bar appears at the right edge which can be used with the mouse. However with a spreadsheet, the scroll bars are incredibly narrow on the external display and difficult to use. Full mouse support would be awesome particularly as I suspect a lot of users will be connecting their iPads to external displays now that the OS is improving.
