Impossible to update Minecraft PE without uninstalling the app in device

When I want to update the game, this shows error in updating

Steps to reproduce:

1. Enter to play store

2. Search Minecraft

3. Try to update to last versión

Expected results:

The game is updated

Obtained results:

The game doesn’t update by “unknown” error

The only one solution to have the last version is uninstalling the installed app and reinstall the game with the last version (my data will be lost after this)
