Hello hello @danielbmeireles , the way to get it back and avoid future reversions is to run
snap refresh snap-store --channel=2/stable
Or if you upgrade your release (as 23.10 is now out of support) it will migrate automatically as part of the upgrade process.
For more context… latest/stable is the original Ubuntu Software app and in previous releases, the new App Center was carried as a branch specific build for each release (eg /ubuntu-23.10)
Because Ubuntu 23.10 is end of life that 23.10 branch expired and moved you onto latest/stable by default.
To more clearly separate the apps we’ve split them into two tracks with 2/stable carrying the Flutter App Center and seeded on the distro going forward. I wrote about this in one of my dev cycle updates if you want to know more: Ubuntu Desktop’s 24.10 Dev Cycle - Part 4: August Update
