How to fix errors when connecting google play services?

Question

Unity

When connecting Google play games plugin 0.9.62, 3 similar errors occur.
The Unity version seems to fit (2017.2.0f3)

Answer 1

https://docs.unity3d.com/ScriptReference/WWW.Escap... - no longer supported
https://docs.unity3d.com/ScriptReference/Networkin... - here is a replacement for it.
You probably have a version in which web requests are still in test mode. edit the conditions or update the unit to the current one.
And stop being lazy by pasting screenshots.
Logs from the console with errors - must be text and formatted (markup and all that)
And a piece of script where errors occur too.
but in general, why is it 2017.2.0f3 ??
take already or LTS version based on 2017.4, it is at least with various support and fixes.
