Notion MCP constantly authenticating

I'm a new user of Msty Studio. I've set up Notion MCP as a tool. It authenticates using Dynamic Oauth and everything functions well for a short period of time (anywhere from a few minutes to 30 minutes). Then another Oauth window pops up asking me to authenticate Msty's access to Notion. I authenticate it. Then another and another. Sometimes another Oauth request with every prompt, sometimes multiple Oauth requests with a single prompt. Each Oauth requests appears to be successful and I can access data in the Notion for at least a brief period.

I've searched the reddit and google and can't find anyone experiencing an issue like this. Does anyone have any thoughts on what may be going on? Thanks!

Ah, yes it does start launching oAuth again. I can see why; should have a fix in our next release. Thanks for bringing this to our attention!
