Best I can offer you is to keep trying with customer support, explaining the situation at each level of support.
After the 90 days, try and change the email again if you can.
1) What you can do depends on the model and type of switch that you have
2) There is always a chance that something goes wrong
3) You might want to look at a dedicated forum for that.
Honestly, my password manager is a godsend. I can see the concern, but for me the convenience is worth it. My passwords are the longest possible based on the individual website, I can store passkeys, I can use biometrics to log in. Highly recommend.
I mean it makes sense from a business perspective especially for the youtube portion. Those videos are likely seeing minimal if any views so freeing up server space seems like the right call.
I love 1Password and have been using it for years. Their IOS and Android apps are great and very well integrated into the systems. The $30 a year is an easy sell.
