We currently have a Smart Lock FW Beta (2.5.0) which adresses some issues. You can test it out by applying for Beta here:
Be aware that you can end beta any time again but not roll back to a previous FW version on your own. And we can not guarantee your specific problems are fixed as I don’t know them.
As I understood you already contacted our customer support which is the way to go if you want your individual problems checked and concrete recommendations about setup/settings/beta-versions of Apps/Firmware that might help.
Please note, that this is a developer forum, support tickets are handled separatly and we are serving this forum beside our regular daily responsibilities.
