Upgrade problem mn3 to mn4 (macos)

A couple of months ago I purchased the third version of the application for ipad and macos. On the tablet I updated to the fourth version - everything is ok, but on macos the problem arose during the initial launch, I chose the discount option, but it so happened that there was not enough money on the linked card, and after replenishment the update did not take place. I am attaching screenshots of the problem.

@Support-Team can you help me?

Today’s update did not lead to anything, the error remains the same, I cannot use version 4.

When will you fix it?
