SRS V2 Lenovo SmartHub 500 - Dropping out of multi-way O365 conferences and rebooting

Yes we have this problem too. Raised it with Lenovo and they upgraded the firmware and replaced the motherboard. MS teams calls are fine, it only reboots with multi party skype calls!!! Monitoring it now to see if the new motherboard had fixed it. Lenovo support is very responsive on this particular issue which is a relief
