I don't remember if it was posted in this thread or on the discord, but his policies were massively popular (+44% or thereabouts for a few of them) but corbyn was underwater by like 40% personally.
But these issues seemed to be backseat to brexit so ymmv. From what i understand labor didn't have a strong message on it until later in the election cycle where libdems were remain /revote and Tories leave, generally.
