Microsoft won't be releasing a new Windows 10 or Windows 10 Mobile build to Windows Insiders today. However, the team does have a release candidate in mind for Windows 10 Mobile, with the build number 10536.
Windows Insider leader Gabriel Aul posted the news on his Twitter account:
"No builds today, but 10536 is next candidate for release."
He later added:
"10536 is in our internal slow ring currently, it's the next Mobile candidate."
As for when it will be released to Windows Insiders, Aul stated:
"We're definitely trying to get a build out this week."
Windows Central editor-in-chief Daniel Rubino has heard that Microsoft is working on fixing "loading" issues for apps and performance in the latest builds for Windows 10 Mobile. Hopefully we will see the results of their work in the very near future.
