It's not just you, but it is erratic.
Initially I saw no lens profiles. Then, as I took more photos, they started appearing in the newer ones.
At first I thought it depended on whether I edited the photo in LR Mobile or not, but that doesn't seem to be it either.
Go figure. Maybe they'll get it more consistent in another release. It always worked with the JPEGs but the RAWs are erratic.
