Hi there!
I just started using Power Automate yesterday to try to automate the inventory process at my job, and I'm caught up on one error that's really stumping me. I'm attempting to send keystrokes to a combo box (this is what the UI picker calls it, I'd normally call it a dropdown) so that I can open it up and select one of the options, and it ALWAYS works the first time whenever I run a flow. However, the second time it's to be run (on the same page, and using the same action) it will always give me a runtime error indicating 'Window wasn't found'. I've tested this both on the production website I'm creating the script for, as well as on reddit and it happens the same way on both! I'll include a screenshot of the test script I made to test this issue on reddit for clarification. Let me know if you need any more info, any help with this is much appreciated!
