We are getting this error when trying to increase licensed seats through the "Modify License" button:

sfLma.updateCustomerLicense: execution of BeforeUpdate caused by: System.UnexpectedException: Element {urn:partner.soap.sforce.com}returnAPIPerformanceInfo invalid at this location (System Code)

Suspect it may be a Summer '16 versioning bug (as the org the LMA is installed into is Summer '16). I've created a support request but would appreciate any insight or work-arounds to speed the fixing process up.

(We are using version 1.19.)

+1 for Salesforce paid support who just replied:

They've identified this as a known issue and are working to resolve this. In the meantime, if you could provide us with the licenses that need updating with what needs to be updated, we can do that for you in the back-end until this gets fixed.

And a day later:

I heard from Tier 3 that the fix went in yesterday. You should be able to make the changes yourself now without Tier 3's intervention.
