So I blocked a device around 3 weeks ago it was my cars dashcam as was having issues with either the unit or mifi dongle so blocking it allowed me to fix the issue anyway my blocked list no longer shows on the eero app so I am unable to block it I have searched the app and online with no answer on how I go about un blocking a device that no longer shows in the block list any help would be great 

Have to admit after paying so much for this mesh system I am not impressed at all and debating sending it back as there is juat so many little bugs and glitches 

Thanks
