SEO issues

Greetings,

I just finished setting up my site and I now went deeper into the SEO and ran into some problems.
My WordPress theme is Blossoms Travel Theme and I am using All in one SEO(free)

My first question is: I noticed that some SEO meta descriptions are completely random and not what I requested to Google.
Now I have read before that Google tends to do that and there is not much to be done about it..
But what I do find weird is that: on mobile and desktop there are 2 different meta descriptions.

For example I recently reindexed this URL: [ redundant link removed ]

It might have fixed my meta description on desktop and implemented what I came up with but on mobile it is still as before.
Why do I say might? Because when I type on Google I see the correct description but when I copy and paste the URL of that page on Google it shows me my old one?
And the mobile one is even completely different than the other 2
So my question is, why is it possible that I see 3 different meta descriptions on 1 URL?

Another question I had was: some SEO meta descriptions that I came up with myself were implemented on Google search results.
While others are being completely ignored. (While I’m sure what Google chose is way worse)
I tried changing my meta description on this page 3 times for example, each times updating my meta and uploading it on the Google Search Console

Kind regards,
Dave
