Rapi Bundles Builder & Upsells

We have tested various apps for bundles and have also used Rapi for some time. In itself, the app is good, despite the limited range of functions - after all, it's free. Nevertheless, we ultimately decided against it because there was a issue that bundles did not work at all (“Don't worry, it's just a sync problem”) that was not solved for several days. In addition, the support initially requested full access to the entire store, which was unacceptable for us. We don't run large stores and don't have a lot of staff, but we still (or perhaps because of this?) need them to work as smoothly as possible.
