From a Pro Software Developer -> Huge Scam
Huge scam. I am a professional Software Developer and have been contracted by a few of smaller clients to use Groove. Whenever I hear that a client wants Groove as their platform I highly insist against it. I have never heard anything good about them in the engineering world and have never had a good experience myself. Mind you, I don't spend any of my own money on this platform so I am not saying this out of bitterness.
Run far away from this product. They over-promise again and again with the same rotation of promised updates so they can increase sales quickly, but they know sure and well that they do not have the capacity to deliver on those features. No dev team of this size can acheive what they are claiming to build, and it shows in their delivery.
Behind the scenes, many of their higher ups have resigned or been fired, and they have high turnover with their dev-team. There are confirmed reports that they aren't paying affiliates. They also promise life-time access to clients, which some have mentioned being locked out of their accounts after some time. Clients I worked with didn't even have access to certain features because Groove servers were down for WEEKS, causing them to miss out on vital sales periods before Christmas. These are screaming red flags. If an app is broken, it SHOULD NOT go to market. And yet Groove is marketing this as if it is a completed project with no issues.
In my experience working with Groove, I had to report bugs EVERY SINGLE DAY. And I am speaking of large bugs that prohibit progress. The GrooveKart server was down for weeks, so my client could not upload products to the store, missing the window for Christmas sales. When adding content to the website, it would often give a confirmation that it had saved, only to not save any of the work we had done. And you had no way of knowing if it actually saved or not until you left the site and came back. This was hours and hours worth of lost time having to push through this bug that can only happen through blatant negligence. Other problems experienced could only be caused by an inept dev team: being able to add content and not being able to update or delete it later. Admin features not being accessible to different screen sizes or browsers.. in other words, if you didnt have a certain laptop then parts of the admin dashboard didn't work or were inaccesible. Then there are the crashes, the extremely slow speed, the lack of tutorials or documentation, the servers being down for days at a time with no warning. Etc. And most horribly, they have stopped customer service altogether so if you have an issue or want a refund you will NEVER GET A RESPONSE BACK.
Please do not invest any time or money here. I wish they would get shutdown so they would stop scamming people. I sincerely feel bad for my clients and people who spent money on this. Groove should be tried for fraud.
