Can't download app Error code -506

[Myllil 0]

I have android 8.0. Repeatedly getting Error Code -506 message at the final point of installation. Ever note was previously on my phone until I had to do a full restore of my phone recently. All other apps are downloading without issues. I have already done the suggestions on Google Play help.

Thank you in advance for any advice.

Hi.  Haven't ever seen this particular error myself,  but a web search had over 2M hits so it seems quite common. 

In fact this page - https://www.maketecheasier.com/fix-error-code-506-google-play-store/ includes

It’s a fairly common error that is caused by multiple versions of an app creating a closed loop. It is not a problem with the app you are trying to install.

I'd suggest you work through some of these fixes and see whether they do the trick...
