SleekFlow failed to meet the basic standard of a decent app. What is good about SleekfFow if this app automatically logout from your S24 Samsung phone every day, and you have to pay a few hundred dollars extra to gain their WhatsApp CS support but in the end realised you're actually paying extra to become their app tester. Sleekflow has a lousy user interface, consistently log out resulting in user not able to be notified of incoming chat. Yes, they do have an efficient support team (I paid extra approx. RM400 per month for that) yet an ineffective one as they are not able to solve the most basic technological problem. The worst is, user gets frustrated having to collect log for the tech team every single day and forced to stay with Sleekflow as user can't effortlessly change provider due to ongoing contract and also the cons of switching. SleekFlow is a WABA service provider that cannot even meet the basic standard of a decent app. SleekFlow is definitely not at the forefront of innovative tech as claimed in their press statement.
Using it to integrate with WhatsApp Business API- poor self-serve support- support / CEO / CPO did not solve any problem; only answer all bugs / questions / requests is to upgrade to a pro plan- changed my plan after paying for WhatsApp API service; feel cheated- has a lot of bugs including payment link to buy the pro plan does not work
