Possible virus
I had an iPhone 8 and was getting these weird notifications from my calendar app that had links connected to them that seem like viruses/spam. This was going on for several weeks. About 5 days ago I got the iPhone 11 and I am still having this problem. I don't know how to get ride of this and it is a brand new phone so I don't want it to already have a virus.
iPhone 11, iOS 13
