Subconvexity for Symmetric Square L-functions off-centre

Let $p$ be a prime. Let $f$ be a holomorphic modular form of level $p$ with trivial nebentypus. We prove the bound $L({\text{sym}}^{2}f,\frac{1}{2}+it){\ll }_{f,\epsilon }{p}^{1\mathrm{/}2+\epsilon }{t}^{3\mathrm{/}4-1\mathrm{/}12+\epsilon }$. This bound is subconvex in the $t$-aspect and almost convex in the level aspect simultaneously.
