Installed for greater than one year. Installed to a most difficult location and the only lock that would. I agree the access through the Tuya app is disappointing and lacks needed enhancements. Mine does not unlock via the app which is limiting. None of the ways the app is said to integrate works, ie. Temporary pass codes, unlock commands, etc do not work. Alexa integration would be welcome also.
Jake - mine locks from the inside by rotating the handle counter clockwise and unlocks by simply turning the handle normally, clockwise. If yours doesn't do this, ensure the latch bolt fully extends into the door jam when closed. Try it with the door open.
