Please can you confirm whether or not Tedds is compatible with IE11, and if so are there any known limitations?
Yes, the software is compatible. I have checked both the 2014 and 2015 versions of the product, but there is no mention of compatibility with Internet Explorer 11. However, Internet Explorer has a compatibility mode that you can load when you access a website to enhance the browsing experience.
You can browse the pages as well, but if you need additional confirmation, contact the developers of the software:
