Ring Pro directly to transformer, frying transformers.

Hello Everyone! I just purchased the Ring Pro/Echo 5 combo deal off Amazon.I did a ton of research and saw that I needed at least 16 volts AC and at least 30 volt-amps from my transformer. I realized my old transformer was not sufficient so I purchased this unit. It matches the specs required.[https://www.amazon.com/gp/product/B07Q1GRHLH/ref=ppx\_yo\_dt\_b\_asin\_title\_o02\_s01?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B07Q1GRHLH/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1)I followed these instructions which is straight forward. It doesn't mention using the extra resistor box that came with the kit at all when you are bypassing the inline chime.[https://support.ring.com/hc/en-us/articles/360000081206-Installing-your-Hardwired-Transformer-Kit](https://support.ring.com/hc/en-us/articles/360000081206-Installing-your-Hardwired-Transformer-Kit)Everything seemed to work fine for a couple of hours but then everything went dead and I didn't get any more power out of the transformer.At this point, I thought maybe my transformer was bad from the beginning. So I purchased another transformer.Same exact thing happened it works for a couple hours and then fries the transformer.Last reported voltage says good.Last reported signal strength says RSSI-34So now I am like $40 in on new transformers I am thinking the doorbell itself is some how back feeding power into the transformer. There isn't anything else I can think of why it is burning out the transformers? Is there some setting on the ring pro that is back feeding into that transformer? Is there something additional I should have wired up that is not shown in those directions?I think there is something wrong with the ring doorbell itself.Thanks!
