I have been long time user of quicken, going back to the 90's.
I can't belive that QUICKEN has not been able to resolve this issue. It has been reported for years. See on of the posts from 2018.
https://community.quicken.com/discussion/7736086/paycheck-split-values-are-gone#latest I had this issue again after trying to Sync to the WEB Quicken. I was hoping to use the update web features, but after setting up the syncing to the WEB, I had multiple paychecks that were either duplicated, some were deleted and all of them lost the transfers to various accounts.
I had to restore my quicken file from a backup as this caused a hug issue with reconciling my various accounts.
Do I need to have my current Online Quicken records deleted an try syncing again? How do I do this?
Does WEB Quicken file not like transfers to accounts that are not synced on WEB? I do transfer funds to various accounts 401K, HSA, etc that are not synced to the WEB.
