You’re welcome to join those of us who are perpetually teetering on the fence on that issue.
The issue of sedevacantism has fascinated me for a long time.
It's difficult to navigate between the serious flaws I see in sedevacantism (i.e. doesn't it presume that the Holy Spirit has abandoned the Church, and, if this is the case, how and when is the Holy Spirit to return) with the extremely troubling issues I have with Francis and many of the bishops.
My very first thought two and a half years ago when Benedict XVI resigned/retired was that there was something seriously wrong. The papacy is a solemn office, not something to quit at any time.
History is replete with "bad" popes (notably those from the 15th and 16th century) who used the papacy as an instrument to acquire power and wealth for themselves and their families; however, they DID NOT teach dogmatic error. Francis certainly doesn't seem interested in any personal power or wealth, but he has almost certainly embraced the modernism so wonderfully refuted by Pope Piux IX and Pope Saint Pius X.
It is interesting to consider that Pope Alexander VI (a man who nearly all agree embodied corruption and greed) was far less harmful to the Church than Pope Francis.
