There are no limits to the number of screens you can add to your Marvel projects.
If your upload is failing on web browser there are a few things you can do:
- Open a new private/incognito window in your browser and try the upload again. This temporarily disables ad blockers and plugins which may be interfering with the upload
- Check the format of the file you're trying to upload. If it's a Sketch file, you can use our plugin to send the artboard to Marvel. You can't currently add Sketch files by direct upload or drag & drop but this is something we're working on.
- Does a file with the same name already exist in the project? If so, Marvel automatically replaces any images that have the same name. If you want to add the same image twice, change the name then add again.
