Does anyone have 2 of these pumps that have had successfully linked them together? There's no videos out there that I can find showing how to use the app and link atleast 2 together. It seems pretty simple when you open the app to add 2 powerheads and link them BUT THEY'RE NOT. I've gone over this for hours and days and it's so frustrating. Hoping someone here on R2R can tell me how to get them linked finally.
