SL Bridge and Protools issue

Hello
I’m working with SL monitoring it trough AAX Bridge in Protools.
It works fine when I first start Protools and SL, but if I shut SL and reopen it, it seems that SL lost every communication with Bridge, it gives me the message:

“No external application device found. Activate SpectraLayers Bridge in an external application or select another device type in Preferences/Devices”.

I must shut off Protools and reopen both PT and SL again to have sound back again.
I already click the speaker button in SL edit plugin but nothing change.

Best,
Mirko

OSX 10.13
Protools Ultimate 2018.4

Thanks for reporting, will try to repro here.
