Hi Daniel12m & Corm76,

I've pulled up the following investigation for this issue - INV-45625 IOS iPad App - Unable to customise date range of Profit and Loss Report and our developers are working to restore this functionality. The workaround while this is in progress is to use the  iPad browser temporarily to be able to change the date range on the report, please get back to us below if you'd like to be added to the investigation so that you'll receive email notification once fixed. 

Thanks =)
