I think the big thing is "you got less keys" not "you got a split ergo keyboard". I tried a 96% keyboard, but realized that I missed and used the few keys that I lost. I have since decided I want "all the keys" and found a 100% keyboard that I'm more than happy with.
If you are thinking of moving to another keyboard with fewer keys, you may want to to do something to keep track of if or how often you are using those keys that you'll be missing. Force yourself to use key combinations on your current keyboard instead of those keys specifically on your current keyboard and find out if it is doable before making the purchase.
I've had the app lock me up before. I tried to get a little too secure too quickly. Lessen up the security unit you get signed into the app, then crank up the security. If you turn up the security too much, you can't toggle to get your 2FA code.
