The most common Personizely complaint: price
App has a glitch which causes the cart no to function properly. Another glitch causes the app to install in backup versions of your theme. This caused a myriad of issues and an expensive process for diagnosing. Support was friendly, but seemed to either not completely understand the issue or lacked understanding on how this affected us with regards to time/money. They offered a discount, but…
The most common GemX complaint: support
Tracking is inaccurate even after 24 hours. The app doesn't collect data on orders or visitors at all. I wasted two days testing only to see results that make no sense and don't match reality. Support doesn't exist. The support app itself doesn't even work. No way to get help, no responses, nothing. Stay away from this app.
