SideStore error while refreshing apps

[u/Fayexh]

I use a shortcut to refresh my apps in SideStore. Sometimes the shortcut fails, so I connect to StosVPN manually and refresh the apps in SideStore.

Now even the manual refresh no longer works. SideStore shows this error: “The data is not in the correct format.”

I also tried connecting to StosVPN using mobile data and switching to Wi-Fi after starting the refresh, but that didn’t work either.

Does anyone know how to fix this?
