There are clear and direct Biblical teachings and prophecies and promises regarding the ongoing works, gifts, and power of the Holy Spirit in and through the entire church--as the living Body of Christ.
These are clearly delineated by Christ's example and His instructional impartations of the Holy Spirit in the Gospels, and later--permanently-- after Pentecost... in the book of Acts...
These are clearly constructed by Christ himself teaching the disciples to EXPECT the promise of the Father -- the beloved Holy Spirit (John 14-16)
-- And especially reminding us that all the manifest glory and power will be Christo-centric ( John 15:26)
None of these Biblcal teachings, examples, prophecies or fore-telling promises describe the appearances of Mary ( or anyone else), or the expectation of any miracles given as gifts or rewards for the testimony of her(/their) apparition.
(The holy angels remain active as messengers--commissioned only by God-- as we see in the book of Acts)
None of the promises tell us that glory will/should be given to Mary... or any one else... (Isaiah 42-44 are worth a look!)

For your info & perspective--
Sola Scriptura is only the first of five pillars of sound doctrine: (as follows)
(1) Sola Scriptura: the Bible is the only inspired and authoritative word of God -- FIRST... FOREMOST... and FINAL
(2) Sola Fide: Salvation is by faith alone -- not by works (Eph 2:9-10)
(3) Sola Gratia: By grace alone -- the favor of God given to Christ-- and those found in Him
(4) Solo Christo: IN Christ alone... (Acts 4:12)
(5) Soli Gloria Deo: For God's glory alone--presently and ultimately

No, it is not providing answers.
It is setting grounds for rational discussion.
Sola Scriptura is only the first of five pillars of sound doctrine: (as follows)
So you say. I say it is itself an unscriptural absurdity, and a guarantee of false doctrine.
What is the "pillar and ground of the truth"?
