How to update Vertex 4.3.1 to 4.3.2

Hello, I am in process of updating a Shape 5 Blogbox site from 4.4.4 to 5.1.

I see there is Vertex update available to download on your site, but the site itself says "Latest Version 4.2.5, template installed 4.3.1". Therefore it does not give me opportunity via Shape5 Vertex Updater to update to 4.3.2.
I have not yet installed the latest Blogbox template. Should I install this first, then will it allow update to 4.3.2?
If I update all other available shape5 extensions to latest, can I safely update to Joomla 5.1?

Thanks 🙂

I recommend to update latest versions for template and its complimentary extensions before updating to Joomla 5.1 🙂
