Indoor cams constantly alerting - now intolerable

I have 2 indoor Cam gen2 and StickUpCam Pro. Pro is still currently working OK. The two indoor cams are now both in constant motion detection alert melt down. Changing zones / unplugging to reset / anything else is having no effect. Reading threads I am not alone. This needs to be sorted IMMEDIATELY. Currently the product is not fit for purpose and I am now consdering de-comissioning and replacement with an alternative solution. I've only had a few days of proper usage before whatever change has occurred has rendered the system intolerable. I have another StickUpCam Pro not even opened yet - there is no point .....
