Same old, same old Netflix Error Code: S7363-1260-FFFFD1C1

I'm aware that many, many people get this Neflix error message ( Error Code: S7363-1260-FFFFD1C1) when using Safari, so I'm restating the obvious. I've searched for and tried many solutions...I have found only one reliable fix, and that is to shut down Safari, go to the library folder and trash the Netflix IndexedDB file, then restart Safari. But this is not a PERMANENT fix, since you have to do it every 5 minutes that the error occurs.

But WHY should I have to go thru all that every 5 minutes?! I'm a long time Mac user, and WANT to use only Safari, but this problem forces me to use either Firefox (RAM hog) or Chrome (which I don't like). I feel that Netflix should be obligated to fix this since so many users are involved. So, Apple, how do we get Netflix to take this seriously?

It happens for me every single time I try to go "back" to a previous segment of something I've already watched. I'm using a MacBook Pro 15-inch, High Sierra 10.13.3, Safari 11.0.3.

Does anyone have a permanent fix for this Netflix / Safari problem?
