Steam Changes August 29th 2019

This is pretty stupid. Sure I can log in the the game by clicking on ffxivboot in the game files. But clicking on 'Play' in steam doesn't work.
Is there a fix to this?

Unfortunately we're in the same boat, and we're the only ones actually effected by this change, not Steam account users as was the original intention for the change as outlined below:

[Important]Regarding FINAL FANTASY XIV Steam Version (Mar. 8) (Updated: Mar. 13 11:05 p.m. PDT)

As part of our fraud prevention measures, we plan to implement a restricted login check process for Steam service account users.

[Affected]
FINAL FANTASY XIV Steam Version

[Changes]
Current:
FINAL FANTASY XIV Steam version clients can currently be opened directly without going through the Steam application and is possible to use the regular Windows version client application for Steam version service accounts.

After the change:
For Steam version service accounts, the FINAL FANTASY XIV client application will need to be started up from the Steam application's Play button. Any other method of direct startup will no longer be available.

[Time and Date of Implementation]
Late March 2019 (tentative)

*Update Mar. 13, 2019 11:05 p.m. (PDT):
Due to a confirmed bug, implementation that was tentatively scheduled for late March will now be delayed until April or after. We will let you know as soon as a date is confirmed.

We thank you for your understanding and cooperation.

Steam users can already add "-issteam" to the launcher options and still launch the game outside of Steam, while folks in our predicament are the only ones actually blocked.
