I could be mistaken here but I think the problem might be this:

>In EA’s earnings call, CEO Andrew Wilson said that EA and the development partner chose to sunset this “version” of the game and that the company has “plans to reimagine a connected Apex mobile experience in the future.”

Basically "this version isn't working out so we're starting over and if you supported us up until this point tough luck".

I also assume this different version doesn't transfer into the main game on any other platform.

I can understand people being a little annoyed by this.
