I’m abroad. I’ve used an application to determine the direction of the Qibla and have found that the direction of the Qibla in the mosque is off by 15-20 degrees. I’ve raised the issue to management but they give any mind. So at the moment I pray with the Imān..

Shaykh Ṣāliḥ ibn Fawzān al-Fawzān:

Do not be harsh. The Prophet ﷺ said: “Whatever is between the east and the west is Qiblah.” a slight deviation [is fine] as long as the Ka’ba isn’t behind or on your side, it doesn’t harm you.
