IFTTT-Trigger not working correctly

The IFTTT integration no longer seems to work properly since a few weeks (?). According to the IFTTT protocol, both the trigger for unlocking (!) and for locking are triggered when locking, but no trigger is triggered at all when unlocking.

Any idea how to fix that?

If you send me your Applet user ID (not the general Applet ID!) via PM I can check for error codes in the IFTTT logs (for the last 48 hours) to check if I can directly find anything.
