IOS App Side file name panel not showing full file names

Mostly on IPAD’s we are seeing an issue were we can’t see the full file name on the left hand side of the app. On IPhones if you turn the phone horizontal you can see the names. We tend to have long file names in our Catalog of which we use Nextcloud to give our sales guys access on the road. Would like the Side Panel to be adjustable to see the longer file names if possible.
