Using desktop version Quicken Personal & Business. Have been synching several cash & credit card accounts to the iphone app for a few months. Just tried the web version, and those same account balances don't agree to either the desktop balances or the iphone balances… Have been using Quicken since 1992 & regularly validate, etc. The issue seems to pertain to incorrect opening balances. Data for phone app/web is only visible back to 2017, which is fine. However, the web version seems to either have 'bad math' or is missing some of the 'hidden' history because three of the account balances are incorrect with differences originating with the first web version 'visible' transaction on May 1, 2017 where the desktop balance for one of the credit card accounts shows $182.54 vs the web balance is $98.36, a difference of $84.18. This agrees to the current balance difference in the same account after both 1) validating the desktop data and 2) re-synching. All three of the accounts with differences (one checking, & two credit card accounts with either Chase or Bank of America) have been fully reconciled to the most recent bank statements in the desktop version. Thoughts?
