UPDATE:

Since the release of the Firebase JS SDK Version 9.18.0 on March 16, 2023 it is possible to combine several in clauses in a Query.

However note that "Cloud Firestore limits a query to a maximum of 30 disjunctions in disjunctive normal form", as explained in the documentation (which includes examples on the number of disjunctions for different types of queries)

OLD ANSWER:

This is indeed a limitation of Firestore, as explained in the documentation:

Limitations

Note the following limitations for in and array-contains-any:

• in and array-contains-any support up to 10 comparison values.
• You can use only one in or array-contains-any clause per query. You can't use both in and array-contains-any in the same query.
• You can combine array-contains with in but not with array-contains-any.

 this.messages_collection = this.afs.collection<ChatMessage>('messages',
  ref => ref.where('email', 'in', [this.user.email, this.receiver.email])
    .where('receiver_email', 'in', [this.user.email, this.receiver.email])
    .orderBy('timesent')
