Hi, I am currently running qiime2-2019.10.
When I attempt to export PCAs from Emperor, I only get the plot and not the legend. I have tried on many different browsers and on other PCs as per a previous closed thread in addition to re-generating the .qzv from the same qiime2 version. I tried again, using a .qzv generated from qiime2-2019.7 using the exact command with the exact same data and reloaded that in to Qiime2View. I was then able to download both the legend and the plot from the visualisation. I suspect a possible bug in how the .qzv files are handled.
