I am still mergin all my libraries over from Aperture to Lightroom

I stuck with the old dog as long as I could. Halfway through doing this, I sold both my computers to upgrade (2015 IMAC5k, 2012 MBP) - So my Lightroom workflow is still in the early stages. Mostly at this stage using classic, I am just taking time to organise my files ready to start a new year.
I just bought the new IPad 12.9 to try to figure how to use it in my workflow. As i photographer I really see it as a portfolio you can take anywhere, I have a massive stock library and to carry a range of shots in such a beautiful way daily makes me feel warm a fuzzy. I also think it is the future of photo editing, art, and using apps such as Astropad would like to use it as a Wacom down the track, I think all these areas will improve, hopefully even implemented into the new photoshop release.
At the moment I am without a computer, so cant really work on my Lightroom workflow, about to plunge on the new MacBook Pro, i just don’t have any other option even though the issues are out there.
I have had to do a couple of shoots without my computer, I have imported over wifi (Canon MK4) to iPad, Lightroom cc, also via SD card. I have noticed on many images within Lightroom CC red squares/corrupt info in many images once opened within IPAD CC, the images look fine in PHOTOS app (You must first import to PHOTOS APP before editing in LR)
I am also finding the export settings and compression seems poor, I cant really double check as I feel lost without my computer but the maximum files size I seem to be able to export is around 4-5MB from LR CC iOS, these are coming from a 30MB Raw file.
I must say to sketch my ideas out, Notability is just fantastic. I go from rough idea/sketch, then out in the field take notes, import test images into the note and continue to evolve the idea. Notability got me through my last degree and I still have all the notes synced to this iPad years later. I find that security invaluable, loving the iPad still, wish i could use my trackpad.
