  This paper investigates the effects of spatial curvature in a model where
dark matter and dark energy interact. The analysis employs a range of datasets,
including CMB, BAO, Type Ia Supernova, $H(z)$ from cosmic chronometers, $H_0$
measurements from Megamasers and SH0ES, growth rate data and strong lensing
time delay measurements, to assess the model's fit and explore the late-time
dynamics of the interacting dark sector in a non-flat cosmological framework.
The study indicates that introducing curvature can significantly impact the
Hubble constant ($H_0$) and the structure growth parameter ($S_8$), potentially
easing tensions between early and late universe observations. The observational
data shows an indication for a closed universe. This implies that the presence
of curvature and its influence cannot be neglected entirely.
