How do I get Affinity Publisher beyond 1.7.312?

[DavidSilverSteel]

I am tearing my hair out with Affinity Publisher Beta. I make 6 page magazine articles and may have to create a document 3 or 4 times as I cannot overcome problems which seem to occur at random intervals. The problems are to do with trying to put text frames ON TOP of four column text frames. I am about to try to illustrate the problem, but first I need to use the latest beta version which appears to be 1.7.337. I am however using version 1.7.312. When I run the programme it invites me to download a later version than that which I am using. Fine - I wish to download it, however when I follow the link it continues to download version 1.7.312 - which I already have! Please can you help me to download the latest version.
