Hi, Stephen. Thanks for the helpful screenshot.
I was able to reproduce this on my own iOS device, but I’m not sure it’s something we’d consider “fixing” because it actually is a text field. The datepicker makes it significantly easier to insert a valid date (text) format, and it works after tapping “Done” to dismiss the keyboard.
I didn’t test on Android, but this article might be helpful if you want to customize how this text field works on your own site: https://stackoverflow.com/questions/15135784/how-to-disable-keyboard-appearing-when-hitting-on-a-text-field-ios (third-party, not guaranteed or supported by us)
To implement something like that, you might need to follow our Themer’s Guide to customize /wp-content/plugins/the-events-calendar/src/views/modules/bar.php
Please let me know if you have any follow-up questions on this topic.
