Hi I hope someone can help me.. I am using Lightroom mobile for iPad.. my iPad is the iPad pro 12.9 2017 with 256gb of storage. My issue is this.. when I edit a raw image (Nef file from D800) in Lightroom mobile it lags like crazy... When I am making a selective adjustment it seems to take the brush a long time to catch up which makes it almost impossible to do any serious editing. Has anyone else experienced this issue.. I am seriously frustrated with this issue.. I really like the idea of using Lightroom on my iPad but not like this. My Adobe photography subscription is due for renewal on the 25th October 2018 and if Lightroom mobile is going to be like this then I will not be renewing my subscription.. in fact I have already installed Affinity Photo on my IPad pro with a view to using this instead of Lightroom and already I can see a huge performance difference in the 2 ... So it is critical that someone offers some advice before I csncec my Adobe subscription.. Thank you in advance..
