I’ll move this to Samsung Developer Program as it is not a Galaxy Watch issue.
Samsung started migrating to the new store look in November of 2020 and it has proven to be an improved sales method. the Top category is now a banner at the very end of the Galaxy Store Watch Tab, There is the Popular Watch App and Popular Watch Tab which are equivalent to the top list. Basically only sellers care about this.
You will probably find the complaints about finding the category were old ones, originally the “Themes” tab was Customizations and the length of if pushed “Watch” to where it didn’t show.
60% to 70% of the people that open the Watch store come from the Wearable App, very little come from opening the Galaxy Store and then going to the watch tab. Again this is something more of interest to sellers than actual buyers.
The number of downloads and sales since November have significantly increased over same period a year ago.
I hope that explains the reasons and rationale for the changes.
