I think someone else noticed this but every time I put the recall address into the Safari browser menu it gets hijacked and opens up a webpage as follows: https://www.recall.it
Even if I manually enter the web address exactly it re-directs me to 'recall.it'.
I tried opening it in the new 'Comet' browser just to see if it worked there and it also was hijacked.
I then tried the Brave browser, but it was not affected. Kudos to Brave!
