php compatibility

Hi,
I have been using Plainview Protect Passwords with our WordPress site with no problems. At present the site is running under WorPress 4.7.9 and php 7.0.28. I intend to update to latest php (7.2) and WordPress (4.9.4) versions as soon as possible. When I have checked the php compatibility of Plainview Protect Passwords using the WordPress plugin ‘PHP Compatibility Checker’ by WPengine I receive a report with 15 warnings and 3 errors.
Please can you tell me if the plugin will work correctly under php 7.1 /php 7.2 ?

Thanks in advance

The output from the report is:
