Hi bluebirds15 (& Community),
I am pleased to report that we were able to complete the additional work I had mentioned previously during our planned maintenance period last night. As a result, we are hopeful that you will not encounter any more errors of this nature when selecting images for your listings moving forward.
If you encounter any further errors of this nature, please let us know through your open support case on the subject and we will look into the situation further. I already replied to your support case earlier, but was inclined to update this thread as well in case anyone else who has been encountering errors of this nature has been following along.
Thanks again for keeping us apprised of the behavior you have been encountering, and for bearing with us as we have been working to get the issue resolved.
