I have been using SUMO for years, and I can honestly tell you that it is the most illogical plugin ever created!!! I have been using it for years, and this morning I had to email customer support just to figure out how to manage the social media platforms I wanted displayed on my share buttons. That is a 5 second task that SHOULD NOT require any customer support aid what so ever. But the developers at SUMO DO NOT care about user experience. They show no consideration for efficiency, and have built an app that contains settings BUT YOU HAVE NO WAY OF ACCESSING THEM!!!!!!!!!!!!!!!!!!!!!! They now have this stupid dashboard that all it does it take you to and show you visitor stats!!!!!!!!!!!!!!!! You can not configure any part of this app any longer!!! Because apparently the developers who don't even provide a dashboard to settings now force you to use whatever settings, social media channels and subscription boxes they see fit!!!!!!!!!! I couldn't be more done with this stupid plugin if you paid me. I can't uninstall this fast enough. I have been using the free version for over 5 years and I promise you by end of business today I will be paying for whatever their competition is. I may even just go purchase convert kit and grow. TWO SUBSCRIPTION PLUGINS!!!! Imagine what that says right there. I am willing to go give 2 different developers I have no experience with my money over 1 developer I have multiple years experience with!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! UNBELIEVABLE SUMO!!!!!!!!!!!!! CANT EVEN COMPREHEND YOUR THOUGHT PROCESS!!!!!!!!!

After install and activation (no configuration completed) the app had added just short of 440kb to my homepage and 21 external requests. So I immediately removed it again! I'd used it a long time ago and liked it but think I must've removed it back then for the same reason.

You can't seem to be logged in via their /login link as my google chrome crashed every time I tried, it slowed down my website so much it hurts my SEO rankings. In all speed tests, I do horrible because of this plugin. I happily removed it from all my websites and used other, much better alternatives, to their slow and way too expensive service. Never again.

The connect button didn't work at all. Fuck the plugin. Just waste my 1 day.
Kafuumuulampawu 9, 2020
I installed the pugin and first problem was inactive "connect" button. Support said, I can still use the account to customize website. However, the "sharing buttons" (the thing why I wanted to have this plugin) appear only on my phone or in chrome. I tried 3 different computers to open my website and see how the plugin works. If I used FireFox, the buttons never appear.
