If you are going to use the calendar, just as a calendar, then ok. But the moment you want to start integrating things, then everything goes wrong. The new version does not work with gravity forms installed, site breaks. Even their own plugins do not work well together, the API plugin and the divi builder module, 2 of their own plugins, break each other and you site looks like total garbage. The tickets and invoice module is useless as far as invoices go and their woocommerce plugin basically does what it wants after each update, deleting entries, eliminating paypal keys etc. the list goes on. Support is mainly a bot, when they do get back to you, they ask you to describe the issue IN DETAIL, I don't have the time to do your work, test your stuff before you send out updates. Every update just causes chaos, which then takes hours to fix. Perhaps I should bill you for my time as well. Avoid these plugins where possible.
