As I originally reported this problem, I just re-tested this using i012 PWA and it does not seem faster or fixed to me
Here is a simple file and clicking share for the first time, it takes 26 seconds for the share window to appear
Then clicking on ‘Shared’ again to redisplay the link. This took 32 seconds
It displays a blank link followed by a blank ‘OK’ popup
How long should it actually take?
