I just purchased a plugin for AE and when trying to install it it says its not compatible (nothing about AE requirements on marketplace). Spoke to the chat and they said to get a refund i need to post on here - feels odd but ok!
That weird, You should ask refund from the author of the plugin or wait for their update thou. In the mean time you may need to download a previous competible of AE if you still wish to use that plugin.
