I had a different ticket but it was closed as invalid by MissMarzenia [Mojang] saying you couldn't reproduce.  Not even sure I had put it in the correct place.  in any event, I now have video of the issues.

Platform: Xbox One Realm - whatever current version is as of this posting. Survival mode, no cheats, no addons/texture packs etc.

Summary:

After importing solo world to Realms on xbox experiencing weather anomalies in certain areas/chunks.  Backing up/restoring realm doesn't change anything.

including:

*No thunderstorms ever in one chunk - although neighboring chucks will have thunderstorm.  So I don't realize its a thunderstorm unless i visit a neighboring chunk.

*No precipitation in chunk although precipitation is visible in neighboring chunks.  Visiting neighboring chunk may or may not cause the precipitation to start in the buggy chunks - although leaving and reentering may cause it to stop again.

*Snow through solid blocks - always the same blocks - less than a chunk in size.  I currently use it as my weather checker when I'm indoors lol

Videos (ignore the audio as XBox recording got it out of sync - it is fine in game)

Snow inside - starts around 30 seconds - then I trace it up through the ceiling.  If it is snowing outside - this area will ALWAYS snow inside as well.

Bugging precipitation (again audio out of sync you can ignore that):

Note in above video as I move around it snows or doesn't.  This area is always a problem (the same area by the glassed roof).  Additionally, if in the chunk that contains the glassed roof, there will NEVER be thunder/lightening - if I want to detect if its a thunderstorm, I have to go a a neighboring chunk, listen for the thunder, then run back to use channeling trident in this area once I know its actually a thunderstorm).
