Users appreciate the Wordpress plugin's core functionality, particularly its compatibility with WooCommerce and its straightforward implementation for tracking orders. However, there are several noted drawbacks. Many users highlight that critical features such as email notifications and the addition of multiple carriers require a premium version, making the free version seem limited. There are also usability issues on mobile devices where tracking details need to be accessed by holding down, which can confuse users. Additionally, some reported glitches cause settings to reset, disrupting email notifications. Lastly, there are complaints about the manual upload process for tracking numbers, which some users find cumbersome.
