Adobe Spark app not working on iPhone 15 Pro Max

I recently switched from an iPhone 13 Pro Max to a 15 promax and today whenever I went to log into my spark page app to access all of our company pricing, it would pull up the app, but it would not upload any of my projects. All of the icons and the descriptions of the projects are there but when I click on it, it's just a white page. I tried deleting the app to reinstall it and see if that fix the issue but when I deleted it and went to search for again, it appears that it's no longer an option to download? 

What has happened?
