Reliability decreases as UI improves with useful features but needs better support
Apollo.io used to provide much better service before and their UI used to be less clunky. The user experience nowadays is not as good as it used to be. They used to provide more verified emails and numbers, but nowadays, it's not as reliable. We sometimes have to go through other tools to get more information as they have been lackluster in that area. Their information gathering is not as updated as it used to be. They don't have enough information. When it comes to performance, it's a very heavy app now. It takes time to load, stutters, and gets stuck frequently. Previously, it used to be much less laggy and easier to use. The UI live update was good before, but nowadays, I have to refresh the page to see if they had sourced the email or if old information is still being displayed. LinkedIn keeps updating their tools, rules, and regulations. Due to these reasons, Apollo.io experiences bugs, crashes, detail updates, and jumbled columns during updates. These issues are understandable from a developer perspective, but they create minor inconveniences for customers. I would appreciate if Apollo.io could restore the reliability of their email service to its previous level.
