I too am VERY frustrated with pocket queries. I'm a technical person and find them nearly impossible to do.
I create a new query, name it, select all types, ones i haven't found, number 500, zipcode radio button and enter my 5 digit zip, select easy gpx and select a day. I never get anything from it.
This feature would save me hours of time on the site trying to find the caches, print them out and get ready to go caching however I can never get it to work right. This is certainly a feature that makes the payfer part worth it however it could use some help imho.
Also its incredibly frustrating that I can't just click one up and have it run and send me the results. I understand only being able to do some number of these a day (10 would be nice) but please let me 'run it now'.
Note: not lashing, incredibly frustrated and it appears I'm not the only one.
If its user error, please let me know what I'm doing wrong.
