Yes absolutely a problem. I downloaded a number of the premium ‘special gifts’ plugins as I had made a donation but the four main ones i really wanted, not one worked. All required registration. Even though it is under GPL it is not a good thing. I wanted to ‘try before I buy’ as a couple of plugins I want are not cheap but in the end decided to just go and buy them – including Elementor Pro. That is one of the cheaper ones, I recommend just buying it and spare yourself the pain. Good luck.
