When switching between tab Additional Info and some other tab of some Reseller account one can observe the following UI error:
Parse page error: Window BM::Account_MyResellersListXML not found
Observed behaviour caused by software-related issue #PBA-79822 ("Exception in UI: "Parse page error: Window BM::Account_MyResellersListXML not found"").
To workaround this issue it is enough to reopen the reseller from Operations > Resellers menu.
Contact your Technical Account Manager or Pooled Technical Associate at firstname.lastname@example.org in order to clarify the status of #PBA-79822.
