@Anuradha Nanda -

Without providing more details - e.g. how are you accessing Miro, does it happen with all boards or a single board, it’ll be pretty difficult for anyone in the community to help you. If you care to share those specifics you are likely to get some assistance and if things don’t improve, you can always open a Miro support request here (assuming you are on a paid plan): Submit a request – Miro Support & Help Center
