I’m getting the following message is appium console for implicit wait, please help. I’m using appium 1.8.0 on Mac OS High Sierra with Xcode 9.3. Device: iPhone 7 Plus with 11.3 OS

HTTP] {“type”:“implicit”,“ms”:5000}

What is the line of code you’re trying to execute? Also, can you put in the full debug of the POST? Also, what version of the client are you using (Appium 1.8 changed / supported a lot more W3C options, so make sure you’re using the latest and greatest appium client)

I’m trying to execute the below code, using java client 5.0.2. It was working with previous versions of appium, after updating, it stopped working

driver.manage().timeouts().implicitlyWait(5000, TimeUnit.MILLISECONDS);

Below is the debug of the POST, my script executes but fails at a point where app takes time to load.
