Changes made to the mobile design does not reflect on the Mobile Prototype

My team and I work on building web interfaces, while the Desktop and the Tab version of my design work well. The Mobile designs I made for a project do not reflect the changes on the prototype. This is happening for the past 2 weeks (from the 6th of August 2021)
While I have tried all the initial remedies like restarting the browser and my system. It does not really help much. It seems like the mobile design is frozen to some older version in the past and i can’t make any edits to it anymore.
