Alternatives to Roll20 for mapping?

We play a lot of online D&D with friends. Most of the games I play in, use Roll20. I like it fine and don't have any trouble using it.

But for the game I run, literally all my players HATE Roll20 and really struggle to get it to work. It's been more than a year and we are still struggling with how to log on, how to find attacks on the character sheet, etc., and it's not fun to keep doing that. Combat is painfully slow.

When we're not in combat, we don't use it -- but I don't know any other way to manage a battlemap online. There must be other options!?

Suggestions?? How are other folks doing this -- like if you prefer D&D Beyond, what do you use for battlemaps?
