Still not working in 1.19.2 - and there is no ability to even left click them with shears in bedrock/windows10 edition. This issue exist both in my realm and personal creative test worlds. Steps to reproduce: create a creative world on bedrock/windows10 edition (either flat or infinite will work), build up a few blocks to create a block to attach the initial glow berries, manually increase glow berries to desired length, attempt to left click/ left trigger with shears (it will not let you interact). You can outright shear the glow berries but this does not inhibit growth. Optional* you can increase tick speed to limit wait time to see the glow berries grow. past the desired length.
Same issue xbox one - latest version (nt beta) - happens in survival with random turtles as well as creative with turtles I spawn
This also happened to me on my bedrock realm yesterday; I have had two allays leaded for quite some time (one I found in game in 1.19.2, the other one I duped/bred from the original when 1.19.1 was released) and after returning from my nether trip both were off lead. I was able to lead the original allay back again, however, the duped allay is unable to be interacted with with a lead. I can still take blocks from the duped allay and I was able to breed it after this occurred, however, I could not use a lead on it or the allay duped from it. I was also able to dupe the original after this occurred and I could not lead the duped allay from the original either - although I could give it a block.
