Yes!... And thanks for noting your identical problem here. Until you, I thought I was alone with this issue and almost purchased a new router because with the lack of others here and elsewhere online indicating a more expansive global problem, I thought the issue was with my hardware.
I eliminated Amazon (Echo/Alexa) overall as the source of my problem because my TuneIn service disconnects across all Echo devices, but seemingly, only on the commercial stations. C-Span (non-commercial) does not cut out on TuneIn, but CNN and MSNBC (both commercial stations) do.
Since this issue is relatively new to me over the last couple of weeks, I haven't tested this theory thoroughly yet... But if I were to guess, I'd say it may be more of an automatic time out trigger on TuneIn's part to perhaps prompt free subscribers into buying a paid subscription to the service because the drop off doesn't always occur at just a commercial break. Though both CNN and MSNBC do often drop out at or near commercials, the drop seems more timed to roughly every 15-minute interval and independently across all my devices (I currently have 3 Echo Dots, 1 Echo Studio Pro and 1 Echo Show
. In other words, if I ask Alexa to "play CNN through TuneIn" from all my separate devices and 5 minutes apart, all devices will drop CNN 5 minutes apart and roughly after every 15 minutes from the time I asked, commercial or not.
It doesn't make sense to me that TuneIn would cut out on CNN and/or MSNBC at the commercials when that is likely the only source of revenue TuneIn would have available to them as it relates to us free service subscribers.
So far I've not been very lucky finding a solution through Google, so I'm hoping others will read our comments here and come forward with similar drop off issues and have a solution, beyond the possibility of paying $10 or $12 per month for TuneIn... Which isn't a bad service, but not all that great either... And certainly not worth $12 bucks a month. If I had to go with a paid radio service, it would likely be Sirius/XM. Cheaper and better IMHO and works with Alexa.
