For those impacted clients, there is a tool available, which can be run to downgrade that client back to 2019.4. We do only recommend running this tool if you are impacted by this situation i.e. you are prompted upon opening with relating to 2019.5 or accessing the file via the local API. The Tool is attached to this post and does need to be unzipped/extracted before running the AccountRight Hot Fix Tool. Do ensure that you have a backup/copy of the myox file before attempting.
\n
Note: The majority of the clients will be unaffected
Thanks for the followup, Steven, and thanks to mooman79 for prompting the fix.
