I have a new Samsung S8. I'd like to keep using Nova launcher with Teslaunread, but for some reason, Teslaunread simply won't install. Nova launcher installs with no problem. When I try to install Teslaunread, it appears to download, but then the option to Install (rather than Open) appears. After a few attempts, I get an error message that says, "Can't install app... 'Teslaunread for Nova Launcher' can't be installed. Try again and if the problem continues, get help troubleshooting. (Error code - 505)." I have tried most of the troubleshooting tips at that link, but nothing has worked. Has anyone else seen this? Any ideas how to fix this? Thank you.
