Hey @ulrich just a heads up that I was able to solve the problem for both Ubuntu 20.04 and 24.04 using the method suggested in this post - OCRExtractRelative not finding green and pink boxes - #5 by GerardN
It seems that the shades of green and pink are still a problem on Ubuntu (note, the image file I was using is still the one from the “Namecheap” how-to downloadable zip. I didn’t alter it in any way. It worked fine in Chrome on Mac, but Chrome on Ubuntu doesn’t like the shade). Like the post above suggested, I opened the RPA image editor, re-drew the green and pink boxes but instead of saving it I took a screenshot of the image in the editor. Gave it a dpi_168_relative name and it works fine again.
Thanks again for your help.
