Big team channel names not displaying

Channel names on big teams sometimes are displaying the hash symbol and then an empty line instead of the name of the channel. This affects some but not all users, and for users with multiple devices often only affects one of the devices. The channels otherwise work normally. There appears to be no pattern to this issue but it has affected more than one big team of which I have been a member/admin.

This is a screenshot from one of the members of an affected big team, who primarily uses his mobile device.

Start by reproducing the reported empty channel names in a big team, comparing mobile and other devices, and use the linked screenshot as the visual reference. Check whether the issue can be reproduced consistently across affected users or devices. Done means channel names display normally instead of a hash symbol followed by an empty line.
