Membership2 Upgrade Path Bug

HI there, i was testing the Membership2 plugin to create a series of different dripfeed membership plans so that one plan has finite time and expires to next plan see

I tested this and it didn’t upgrade to next plan.

Sajid told me to show you another person with same issue, except I would like the option to keep the previous membership not to delete access to it.

The reason this is an important bug is this is the only way on Membership2 to create Dripfeeding of Menus and Content on a Page.

Also emails are not being sent out when adding people to new plans.

If you could let me know when there is a patch for this

Many thanks
