Yes because it's totally just Apple devices a simple reboot can fix problems with.
Do you even understand why restarts fix problems? Sometimes software ends up in a problematic state, either a scenario the developers and testers missed, or there was a change in the process that is conflicting with something, and so on and so on. Doing a reboot reverts the code back to square one so any issues that were happening are gone.
Here's an idea: Open the Feedback Assistant, and submit a bug report:
Now with Feedback Assistant available on iPhone, iPad, Mac, and the web, it’s easier to submit effective bug reports and request enhancements to APIs and tools.
developer.apple.com
That way Apple's software engineers know there's a problem and can patch it. You have a rough idea of what's causing the AirDrop issue, so file a ticket of it in the Feedback Assistant and how to replicate it, combined with logs of your Mac, so Apple's software engineers can take a look.
Like I said: There are some issues that programmers and testers miss. That's why we have the Feedback Assistant so if something is caught you can report it to get it fixed.
My 14 inch Macbook Pro had audio issues for months so I reported it to Apple and in turn got it fixed. Apple isn't gonna fix the problem if they don't know about it.
Again: Feedback Assistant. Tell Apple this, not us.
My thought is you should've spent your time writing this thread instead writing a ticket in the Feedback Assistant
Which you should do, right now.

You can also provide feature and change suggestions in the Feedback Assistant, not just bug reports.
