Hi, I have the same problem as this post and this followup which was never updated with the solution.
To summarize the issue:
The Web3Auth works perfectly so far on Android Unity Editor. When I tried the basic test on iOS Unity Editor it gave these errors
-apply the Web3Auth script to an object in a scene
-run in Unity editor play mode with build platform set to iOS
For further errors: apply and use a test script to login via Web3Auth, returning to Unity after ‘successful’ login in browser shows multiple of the same error from a different line of code.
Now when I test the authorization with Unity iOS, I still get the first EntryPointNotFoundException from line 69 on start.
But when I actually try to login with an account, the second error does not appear. However, when I achieve a successful login on the browser and return to Unity, the Debug.Log I placed in the onLogin method does not fire.
