Amazon has silently altered its app logo in a bid to make it less problematic, as some customers have found the previous design somewhat controversial.

The previous logo that was introduced in January was supposed to “spark anticipation, excitement, and joy when customers start their shopping journey on their phone,” a spokesperson for Amazon said at the time.

However, what the company did not predict was its resemblance to Nazi dictator Adolf Hitler, particularly, his mustache, which many customers have found uncomfortable.

“I completely missed that amazon quietly tweaked its new icon to make it look… less like Hitler,” wrote Alex Hern, a technology editor for the Guardian, on Twitter.

The controversial app logo appeared to shoppers using smartphones and tablets. CNN reports only customers in the United Kingdom, Spain, Italy and Netherlands saw the “Hitler” icon in recent weeks.

On the new version of the icon, the ragged blue tape – the origin of the customers’ discomfort – was replaced with a two-tone folded one to exclude any possible associations with the dictator’s facial hair.
