[DonJayamanne]

Please can you file a single issue per problem, as that allows us to deal with one problem per issue,

Eg if we fix one problem then we can close that issues allowing people to also work on different issues at a time

[vvilhonen]

Oops, should I remove this and create the issues separate? I see somebody got assigned to this already

[DonJayamanne]

Yes please, that’s fine if our issue assigned
