Smartlink

I wonder if anyone else has had any issues with using a Maestro on Smartlink with 2.2.8 software.  After updating to 2.2.8 I have experienced very flakey performance on remote via smartlink on links which had previously worked ok.  The Maestro itself works fine when connected by ethernet and when on my local wifi. I find that SDR ios on the ipad is working ok on these same remote links but Maestro will not perform properly and will lock up. Sound comes through but the spectrum display shows as per picture below.

Comments appreciated from other remote users running 2.2.8
