On 17 July 2019, Tymon agreed to join newly promoted Portuguese club Famalicão on loan for the 2019–20 season. He was signed by João Pedro Sousa, assistant to Marco Silva during his time at Hull. He made his debut on 3 August in the first round of the Taça da Liga, a 2–0 home loss to LigaPro club S.C. Covilhã, and a week later played for the first time in the Primeira Liga in a 2–0 win at C.D. Santa Clara on the opening day. Tymon made five league appearances for Famalicão before being recalled by Stoke in December 2019. Tymon started against Derby County on 31 January 2020 in place of the injured Bruno Martins Indi as Stoke lost 4–0. Tymon didn't make another appearance again until the final day of the season on 22 July 2020 against Nottingham Forest where he came on as a substitute in the 71st minute and provided two assists as Stoke won 4–1. Tymon became a regular member of Michael O'Neill's squad in 2020–21, making 29 appearances in a number of different positions. He scored his first goal for Stoke in a 1–0 win against Nottingham Forest on 21 August 2021.
