I also have a 130 and have never even looked at the app. I use Roon and have a dedicated server (Small Green Computer i7) and it works very well this way and sounds amazing. I used to use a M1 Mac Mini to run Roon core and that also worked very well.
I thought the software issues Rose had were worked out long ago as I haven't heard of any for quite a while. I don't know anything about the status of the 250 though. Even though I don't use the app I have found the operational interface to be top notch. If there were a button on the remote to turn off the display entirely it would be perfect. The display is amazing, either in meter mode or "what's playing now" mode but sometimes (rarely, tbh) I like to sit in the dark.
So, even if you don't want to use Roon I would agree that using your streaming service's app is probably the way to go. I would also agree that ethernet is a much better way to stream music if it's at all a possibility, even though I doubt the wifi is causing your issues.
