Compatibility with PHP 7.3

Hello, we are in the process of updating our website to PHP 7.3. When running the PHP Compatibility Checker, the Timed Content plugin comes up as Compatible however there are 12 warnings (included below). Is this something that will be addressed with a plugin update in the near future? If not, is it safe for us to update to PHP 7.3 and expect the plugin to still work as designed?

Thank you!
