SAR coregistration not working when using product geolocation

Hello users group -

I ran into a problem using SNAP for coregistration of PALSAR-2 images (Radar -> Coregistration). It worked fine a couple of months ago, and I’m wondering if something changed in a recent SNAP update.

In setting up the parameters for doing the coregistration, I tell it to use geolocation information rather than orbit information. However, when I click “Run,” it says that there is no geolocation information in the file, but the file is a geoTIFF file.

Again, this worked just a couple of months ago, so I’m not sure what has changed. In fact, I tried running the coregistration on the exact same images that I ran successfully a couple of months ago, and this time it failed, so it appears that something changed in SNAP.

Thanks for any help that you can provide…
