Cant sign in or access all lessons

This is to inform our users that we have seen reports of users that either can't sign in or access certain library lessons. We have found one potential cause which is antivirus software products. Some of these antivirus software products have recently updated their definitions (so if you had an antivirus update recently) causing them to flag Minecraft Education Edition as a potential risk and blocking communication. To resolve this Minecraft Education will need to be added as a trusted app and you may need to contact the software company and work with them to get that communication unblocked. Hope everyone is well and learning lots while playing!
