I am also finding this on realms.
Did at test on 1.11.4 build a spawn platform high in the sky 48x48 afked for 4 hours and no pillager patrols.
Outpost seem to work as intend though.
@Darren that is more or less my experience to, one patrol when the up date landed and then nothing 😞 not only have I worked extensively at a village I have also explored quit a lot and I have never seen another patrol.
I am on Win10 with a world that is from the Aquatic Update, my net step is to start working on a village located in chuncks generated in 1.11.X my something will happen then.??
Addendum I feel like this should have a higher priority as it basically renders renders the 1.11 update null and void as with no patrols there are no raids so we can't experience a large pat of the updated content
Playing on Win10 and I have not seen a Pilliager Patrol since just when the feature was introduced. Got one patrol then but none since.
I play on world that was made when Aqautic update first came out 1.4 I have wondered if that had something to do with it but I have been newly generated chucks and still no patrols.
Same problem here no Pillager Patrols to be found... I'm on WIn10 (bedrock)
Just had is bug for the first time, it was while riding a horse and it was just after if fell to the ground after spawning (MCPE-38374) I don't usually ride so I did not mention it in my comment in that bug.
Just had it happen to me, ever been to the End and it was a single player game
This bug also seem to affect the Skeleton Horses
