I really wanted to like this as I have switched from iOS to Android and was excited to us it on my S8. Disappointing at best

(1) lag time for almost everything. It took on average 20 to 25 seconds to erase, write, or zoom and have the page focus.
(2) ease of switching from pen to erasers to shapes was non existent
(3) loading was horrible

I understand this is a beta but considering the ios version is essentially seamless I thought the program would be better prepared to cross platforms.
