My company received an e-mail from Salesforce telling us we'll be transitioning to Lightning in 54 days.
This is pretty catastrophic for us as Lightning Experience is very slow, the interface is unfamiliar and painful to use for our users (and myself.) We simply can't use it because of the terrible performance/ unresponsive and alien interface.
I tried searching how to disable Lightning Experience and came across the following article: https://help.salesforce.com/articleView?id=lex_enable_turn_off.htm&type=5
I followed these steps and this switches you back to Classic and removes the "Try Lightning Experience" link at the top right. Apparently one of our execs needs access to that button to switch to Lightning Experience for some custom dashboard he uses, so switching this off this way is not an option. I have to leave it on and stay in Classic.
I'm worried that our org will be forcefully transitioned to Lightning Experience in a couple months without the ability to switch back to Classic. How can I prevent this?
