Since Disney has no plans to retire the Elena of Avalor, a character from the show of the same name from both of its US parks, as she’ll continue on with the debut of a new cavalcade in a few weeks, despite her show ending on August 23rd, 2020, where Sofia the First made a brief cameo in the series finale, and it seriously made no sense to NOT have Sofia appear daily in the parks anymore, since her series ended in 2018 and was removed from the parks altogether in 2019, but now should be the name to bring Sofia back to the US parks, but has to be paired up with Elena at both Disney World and Disneyland, since they’re from the same creator(Craig Gerber)

They’re both Disney Princesses, that should had been both canon Disney princesses(as Sofia grew older seen in the series finale of Elena)
They both have heart and effort in both shows
It makes little sense to still have Sofia the First series on Netflix, as it shouldn’t stream the series anymore, both Elena & Sofia belong together on Disney+(as the Secret of Avalor three-parter episode are episodes of STF)
They have a timeless appeal with both parents and kids alike
Sofia often had special appearances by almost every Disney princess(except for Pocahontas, and princesses after Merida)
It was a major crime for Disney’s entertainment department to retire Sofia the First from the parks in 2019(and made her the only princess to NOT appear at the US parks)

These are the very few reasons why Disney needs to bring back the Sofia the First character to the parks, to join alongside Elena of Avalor, as she isn’t going anywhere
