@Solla-topee I'm not sure how this is a solution? Has your development team implemented a fix yet? I'm reluctant to re-setup all of my devices only to have everything reset again on the last switch....

I'd like to add that the same thing happened to me about an hour ago. I was setting up two new smart dimmers and everything in my house that's TP-Link (except for the two switches I had just added)...
