Firepot review for Rivo: Loyalty Program, Rewards

We installed Rivo for a couple of months to test it in the background. After testing, and leaving a good review, we carefully allocated historical loyalty point to our 23,000 customers and then launched our loyalty scheme. On the same day Rivo's connection to Klaviyo failed to send updated points balances and that evening without warning Rivo set the points balance of every single one of our customers, including those who had purchase on that day, to zero. The help desk promises a reply counted in hours but we are now on day 3 after reporting these issues and every day we get thanked for our patience and told to wait for an update from the development team. If we had not invested so much time configuring this app I would de-install it immediately.
