Hi bopper40,
Is this happening with any link you try to share from Safari? We want to see if this is happening anytime you try or with a specific link, which can help determine possible next steps.
You could see if restarting your iPad Air could help: Restart your iPad - Apple Support Restarting may seem like a simple step, but it can refresh iPadOS and could resolve this issue.
Another step you can take is to ensure your iPad Air is fully updated, to see if that may help as well. You can check for an update in Settings > General > Software Update. If there is an available update, you'll want to backup before updating as seen in here: How to back up your iPhone, iPad, and iPod touch - Apple Support
This article also shows how to update with a computer if that is your preferred method: Update your iPhone, iPad, or iPod touch - Apple Support
Let us know how those steps go or if you've already tried that.
Take care.
