Plugin doesnt work

free shipping and the shipping classes of the plugin doesn’t work at all. don’t buy the pro version of the plugin yet. the author is highly unresponsive and has been saying “he is working on it” for the past few weeks since I’ve raised the issue to him. after 2 weeks, he asks whats my website login detail to trouble shoot it. i had also purchased the 5 site lifetime updates version at $125 on 24th February 2021! up to today i still cant use the plugin properly on my websites !!

i have been messaging him everyday for a follow up and he hardly responds. it’s ridiculous as i have had to delay my site launch just for this! he has yet to show me that the plugin works to what it was described it to be as he has been offline since few days ago and hasn’t replied ever since i raised the issue on march first week.
