@PaulGiroux1& @Katrin_Hils - thanks for reaching out.
To answer your question regarding the token timeout, it is no longer an issue with the ArcGIS for Power Automate Connectors. We worked with Microsoft to adjust the way the refresh tokens were be refreshed and now there is no need to refresh the connection as long as the flow runs within your refresh token's lifespan.
The Survey123 Connector is different connector using the previous authentication method. There are plans to update the authentication process to alleviate the need to refresh the Survey123 connection every two weeks, but that is managed by another team.
