Ring door bell 2 not charging (hardwire)

I have owned the door bell 2 for some time now , 2.5 years to be exact and now it’s been going dead . it’s from what I have read due to a firmware update ? Its alway stayed above 95 or higher and due to this issue I had to buy a extra battery due to this problem . Is Ring going to fix this or is this a thing where you have to buy more batteries ? I considered buying a pro as its hardwire no battery but I have read there is a internal battery in those and when they die the pro has to be replaced ? I also called support and the person really didn’t know what was going on and I think was just agreeing to what I was asking . The main one was is there going to be a fix and the answer was yes , but I don’t think she had a clue .
