I use a world in a realm (Minecraft Bedrock for Playstation 4) and I activated command blocks before the creation of the world. I had been using command blocks successfully until the last update. Now when I write a command in the block (and I close the interface of the block) the command doesn't work: when I re-open the block interface the command was cancelled. I tried to download the world from the realm in order to change an eventual setting error, but the download stopped at 659.00 mb, so I couldn't have a copy of the world.

Can confirm this bug on Xbox One X and Windows 10 PC as of 1.19.10
Yesterday I discovered a very simple and reliable workaround however: this bug only seems to occur for command blocks with undefined (blank) hover text. In 100% of the tests I conducted, this bug did not occur if a hover text was set. Simply assigning any (non-null) value for the command block's label / hover text property (top left corner) seems to be a reliable way to avoid the issue entirely.
