The core function of Late (now Zernio) is ok. Most of the time, I get an error that some of my scheduled posts did not publish due to an unknown error or any other random reason such as image was not found when I had it attached to the scheduled post and it posted to other platforms under the same schedule so there is clearly something seriously wrong with the platform. That's the app's core function, and errors shouldn't be this frequent! I got one of these errors at least once every two or three days! In addition to that, they keep asking for more money for some small functions that should be added according to the LTD terms below, as I'm on Tier 4:
"All future Basic (Tier 1), Professional (Tier 2), Advanced (Tier 3) or Enterprise (Tier 4) Plan updates.
If Plan name changes, deal will be mapped to the new Plan name with all accompanying updates."

They're asking for a ridiculously high monthly payment of $150 per additional feature that was not released during the deal. I believe a class action lawsuit should be initiated or at least a full refund of all early adopters. I hope Appsumo intervenes before this gets ugly. For reference, see other reviews before me who mentioned the same thing! The deal, at this point, seems like just bait to commit to their system and use our money to develop new features that are extremely overpriced and should've been included under the deal terms.
