JBL Playlist - Funciton diminished after firmware updated

I bought two JBL Playlist. Both seem to have an issue after firmware of two years ago. The Bluetooth function stopped working with all devices beside Smartphones and tablets.

To verify it wasn't my hardware I tested 6 Laptops/Computers with Other JBL Products. They did work. it was only the JBL Playlist which didn't work.

I contacted JBL Support, they state wasn't designed for anything beside smartphones and tablets. Even if their website says "Connect Any device via Bluetooth" and nowhere is explicitly state it was designed for smartphones/Tablets only. The Box has icons which says works with, which seems to be a Smartphone, tablet and Laptop. After two year of fault-finding on my end as JBL Support kept blame shifting, that is drivers, OS or my hardware, I found way to downgrade the Firmware. When I did this the product functions returned and worked with devices in question.

This clearly indicates that the latest Firmware has bugs. I forwarded my findings to JBL, however they still deny error on their part.

The product functionality greatly diminished after a firmware update.

JBL just ignores responsibility for their error.
