Some time ago, Wikipedia was added as an additional source for reviews and biographies. When this happened, some people reported that all of the reviews and bios had gone. Invariably, it was then found that they had updated the Core but not the remotes.
Therefore, I’d check that everything is up to date. The Core version as well as Windows/macOS version should now be 2.0 (build 1232), and the Android/iOS remotes should be 2.0 (build 1219).
Keep in mind that Android/iOS must be updated from the respective app stores, so ensure that they did by checking there.
You can then configure your preferences as explained here, in case you haven’t done this before.
