Facebook has notified Messenger and Instagram users in Europe that some features are not available at this time.
The small message appeared in both the Messenger and Instagram apps of European users this week.
The message indicates that some features are not available to respect the new rules for messaging services in Europe, without Facebook identifying the missing features.
The company reveals through its support pages that the polls on both Messenger and Instagram are not currently available in Europe, in addition to the absence of stickers in Instagram, and the absence of private responses via Messenger.
Other missing features might include a lack of audio, video, and document integration, which means that nothing but text can be sent.
Also missing is the ability to choose aliases, along with the ability to share AR effects in Instagram direct messages.
Facebook has temporarily disabled some of these features to comply with new rules on data use in European Union countries.
The new rules are enforced as part of the national implementation processes that take place under the new Electronic Privacy and Communications Directive of 2002 called the Electronic Privacy Directive.
This directive imposes stricter rules on the use of data by telecommunications services operating in countries that are part of the European Union.
Facebook said in a blog post on the developer portal: As part of our efforts to comply with the new privacy rules in Europe, we are making updates that would affect some developers and companies that use the API for Messenger applications.
It added: As of December 16, many of the APIs for Messenger applications will not be available to developers, companies, and people in Europe who communicate with companies globally.
The changes are affected by all EEA countries, which include all member states of the European Union, in addition to the United Kingdom and the three EFTA countries, namely Norway, Iceland and Liechtenstein.
It is not clear when Facebook may return these features to European users, and a Facebook spokesperson said: Most of the features will return very soon, and we are developing ways to restore lost features in the near future.
