I have been using evolve since it was first released about 2 years ago now but at that point there were some issues with how long certain variables take too load (ie loading times).
The team has done an amazing job over these past two year improving this issue along side adding new features like AI recommendations which is great! Currently we are not seeing any downsides or dislikes from our current customers who use EVOLV daily however if they do find anything please let us know because its always good when things get better :).
