Sonos Roam, a very unreliable product

Hi again comunity, I hope you can help me out 

I made a previous post about the behavior of my Sonos Roam and things where improved, but unfortunately, My Sonos Roam now became so unreliable and so unstable again, since I installed the 14.19 update. The music keeps cutting out using Bluetooth and Airplay, and now after reinstalling 14.19 update  the Bluetooth control is not working properly: When my Roam is in Bluetooth mode, I can’t disconnect it using the back button, it gets stuck in the solid Blue light and keeps paired with my iPhone, so, I have to go to my phone and disconnect it manually. 

Factory reset didn’t work, and here in Mexico Tech support is so unhelpful, it’s a hustle to get an efective solution because 1. They keep telling me that I’m not pressing correctly the button and it’s Wireless interference, Really? First of all, I perfectly know how to pair it and disconnect it from Bluetooth, Well,  I made a Speed test and the page tells me that I have 220.37 Mbps, it sounds really Good, all other devices don’t have any type of Wifi issue, neither my iPhone 11, neither my iPad Pro, Neither my brother’s xBox Series X and neither an Alexa 4th gen that I have in my secundary dining room, and about the Bluetooth, I don’t have any issues with other speakers using the same phone, so it’s not my Internet, it’s not my iPhone,  it’s not Wireless interference, and it shouldn’t be that unstable.

     2. I sent a video to the tech support about the Bluetooth control issue and they want to replace the unit, that’s fine, but the problem is that here in Mexico there is a Sonos provider called Biastara, but they don’t answer the Emails, Sonos tech support keeps insisting me to get in touch with them to get this sorted out, but they don’t answer any Email and I can’t wait more time with a broken Sonos Roam just because a Firmware update ruined again the device, resulting in an unreliable product, at least for me.

 Is someone else facing the same issue with your Roams? I don’t want to return it because I love the sound, but it’s unreliability and unstability is dissapointing me so much.   Any help is appreciated.

Thank you and kind regards.
