Roku App Remote keeps disconnecting to the Roku device

First off, yes, I am serious, the title is accurate 

I've been having issues with the remote function of the Roku app. For some reason, it completely loses the ability to see my device, seemingly randomly. I can be either watching something, or actively navigating a menu, and it'll decide to just stop out of nowhere. The issue should just be to check my connection. Problem is, neither my phone, nor the Roku itself actually lose connection. I know this because if I turn my phone's WiFi off and back on again, it finds the network with no issue. And I've had times where the app can't find my device, and what I'm watching not only keeps going, but can load ads, finish said ads, and go back to my content, all while the app fails to see it. On top of that, looking at the indicator light, it isn't blinking like it would if it actually did lose connection, meaning it's the app that's failing, not my device, not my phone, and not my network 

If you're wondering why I don't just use an actual remote.... It broke. I could, in theory, repair the remote myself, given it's out of warranty anyway, but Roku decided to make it literally impossible to open it. And I don't want to spend $10+ if I don't have to

Here's where my question lies, and it's mainly directed at Roku themselves. How can you allow your own official app to fail this hard? I'm actually serious, if you cared about making your app worth your customers time, you'd make sure it's reliable. But you didn't, and given how much Roku devices cost, it doesn't surprise me quality control on an app is as bad as it is. I am very disappointed, and given you basically have little to no competition, there's not really any other company I could empty my wallet to instead of you
