Universal Clipboard Doesn't Always Work

I have a MacBook Air, an iPhone 8, and an iPad Air 2 and use them all often. One feature that is nice is the Universal Clipboard, where I can copy something from my iPhone and paste on my MacBook Air. It doesn't seem to always work though.

If I am on the same network with my Phone and MacBook for example, and go to copy, it may not work. Restarting the MacBook Air often fixes it, but after a period it stops working again. Curious if anyone else had this issue?

I am not interested in hard resetting either, as setting up a MacBook or an iPhone entirely from scratch is a huge undertaking, as is simply resetting from a backup. I have seen that solution suggested and think if that is truly what is needed to fix something like this, that's a problem.
