Please bear in mind that I managed to download a few mods a few minutes before this problem occurred. So, when I search mods for cuseforge on google it brings up a page and I find the file for the mod but then when I click the "install with the curseforge app" button it doesn't download and the page where with "click here" comes up but I can't click on it. I also can't just download them cause the mods I want need additional mods to work but I don't know what those are.
This feature has always been a bit iffy, easier to just make a custom profile and download the mods you want using the apps "add more content" feature. The app should also download any dependencies needed automatically as well, if the author tagged them correctly.
