All bank statements for the 12 months of 2016 were imported to Manager.io before any Bank Rules were created. After having Bank Rules activated, I found that 4 months (March/April/May/June) were still in suspense. Why is that?
It is impossible to tell without seeing the bank rule definition and the entry screens for the transactions in Suspense. I suspect you simply did not check all transaction boxes before clicking Bulk Update.
