We have a basic login check that works with WPM recorded test but not with a transaction script. When I look at the user agent string for the WPM test:
Mozilla/5.0 (Macintosh; Intel Mac OS X 12_2_1) AppleWebKit/537.36 (KHTML, like Gecko)
WPMRecorder/2020.2.6 Chrome/87.0.4280.141 Electron/11.3.0 Safari/537.36 PingdomTMS/2020.2
and compare it to the user agent of the transaction script:
Mozilla/5.0 (Unknown; Linux x86_64) AppleWebKit/534.34 (KHTML, like Gecko) PingdomTMS/0.8.5 Safari/534.34
I can see that the PingdomTMS versions are vastly different and I wonder if the latter needs to be brought up to date.
Here is another, public-accessible example:

And here is a transaction check that is designed to fail so that I can look at the screenshot:
Go to URL https://ember-learn-super-rentals.herokuapp.com/ Wait for element #doesnotexist to exist
