Token-to-sheet link works, but not sheet-to-token?

Hi Everyone, im new to this whole DND And roll20 thing, but I am trying my best. I started a new game with the DND Starter pack module "Dragons of Stormwreck Isle" where already 5 characters are prebuilt. These characters also have a token linked to it. If I for example change the current Hit-Point value in the token, the changes are applied to the character sheet as well, which is good. When I am using the Roll22 Companion app to change the current Hit Points, the changes are also applied to the character sheet, good again When I am Changing th hit points directly in the sheet, these changes are applied to the companion app and the token, also good BUT Why the hell does the shown token value of the hitpoints not change, when i am making changes to the hit points  in the companion app ? Thanks. EDITED: Changes to the sheet directly effect the token, but changes in the companion app not

When you are referencing the Roll20 companion app, do you mean the mobile character sheet app?  If so there has been a limitation with that app for a long time that it does not push changes to HP correctly. 

Ah, good to know. Would bei even greater If they could Tell you in the App about this known issued. Anyway, thanks a Lot for Sharing this information
