The mobile app tells you that mobile BPs are not available on this route.
you are quite right, seems i did OLCI and printed it instead

You should be able to get your DME-LHR bp before going to do your visa check before your LHR-DME flight - I could only get the bp by printing online since mobile bp wasn't available for DME-LHR.
