Hello, I have been using "University - Event app" template for my app and have been working on for 1 week for my project. Everything was working correctly until this morning. My app cannot be published and I am receiving the "We detected that you are using a modified version of Atlas UI for your theme. Please check 'Troubleshooting Atlas UI Changes' to ensure your theme is fully compliant with Mendix 8. Right-click to see more options." error. I didn't upgrade to the newer version because I didn't want to. It was upgraded automatically last night or early this morning. I spent so much time creating this app and I need to finish it by tomorrow. I need help fixing this issue. I tried to follow the steps in this article (https://docs.mendix.com/refguide/migration-atlas) but it didn't work. Any idea how to fix it? Thank you in advance!
Remove any css you may have altered outside of custom.css, and instead, place that css inside of custom.css
You may need to do a bunch of tweaking to makes things work now like css selectors/extra specificity, use of !important (avoid if you can) etc.
