 [EDIT] Looks like the issue linked above does match my issue, so I'm adding my comment over there as well. 

I've had the same issue on Win10 on my realm. I was able to log in to my realm on the iOS version and update the signs, but the formatting wasn't correct–all the linebreaks disappear. When I tried again on Windows 10, the text appears on the sign for a little while, then disappears. Today the text just appeared for a second, other times it will stay until I leave the area and come back. 

I also haven't seen any bees or beehives in any of my bedrock worlds for several months. I think the last time one generated was a few versions ago. All of my Java worlds have multiple hives in the expected biomes, though. 

 [Update] I've since found one hive in a newly generated chunk in bedrock.
