I use tags extensively on notes across multiple notebooks. Up until recently, I used "filter by tag" to help search related topics that might be spread throughout different notebooks. However this functionality isn't working for me at all anymore.
Eg I go to add the tag "mailer" to a note - I can see that the tag has been used on 227 other notes:
If I then choose "filter by tag" I expect the results to list all 227 instances.
Instead, it returns two (2!!) results chosen seemingly entirely at random from my notebooks, although it knows there are 228 instances of the tag:
Am I doing something wrong?
