No seamless tileable images

Hello everyone,

I am working with the newest version of Topaz AI and am running into a huge problem. I am trying to upscale images from 1024px to 3600x3600 pixels using Topaz. Running a few enhancements, etc.

In the original size, they are seamless but, of course, blurry. Now when upscaled to 3600x3600 pixels, they look sharp and beautiful, but are not seamless anymore.

I tried the workaround that was given here in the forum but also did not work. Will that issue be solved in any of the coming updates or is it a general problem with AI upscaling?
