Can anyone tell what the first link's anomaly is about and what the workaround is supposed to fix?

I applied the clock control fix and the ESB timing fix, and that seemed to fix the issue! Clock control fix by itself might have done the job, but I ended up adding both. Thank you very much!

Hi,

I suspect that you are seeing an issue that we have discovered and that will be updated in the next SDK releas. The workaround are in this and this pull request.

Edit: Another issue is fixed here, which is also a potential explanation. This is in main but not yet in any release.
