Firstly! The price is expensive. There would be something to pay for. There are a lot of bugs, but they are never fixed. Only minor bugs are fixed. There are many problems with usability too. It seems that the developer deliberately creates errors and does not fix them, in order for us to use the program it would be inconvenient and we would have to wait for new updates in the hope that these bugs will be finally fixed. As if the developer is playing a tricky game with his users. Secondary! Using the program is inconvenient due to the presence of mocking bugs and shortcomings. So, by the way, most applications on the Apple platform. Some settings are impossible to change, and the default developer settings are terrible. As luck would have it! Thirdly! The default settings are not ideal. It takes a lot of time to work on the calendar settings. For the record, this is a drawback of all applications for Apple. In Windows 7, for example, just click next, next, next in the dialog box, and You be sure that everything will work perfectly. Because Windows applications are fine-tuned, and Apple applications are raw and of poor quality, like an eaten spoiled apple. Fourthly! The Support does not work at all. I have repeatedly written to the support about my ideas for optimizing the calendar, but not a single piece of advice was taken into account. The developer doesn't care about the consumer.
