I am an Android developer and I use webviwe redirect. Most of the time I cannot log in and authorize, but sometimes I can log in and authorize normally. How can I log in and authorize stably and successfully or troubleshoot the cause of the exception?

my email: zdt_gz@outlook.com

Screenshot of the problem:For business reasons I cannot post the login link I generated

I have contacted support@strava.zendesk.com but they said I need to ask questions in the community.

I can log in normally on the Strava app
