A Title Much Cooler Than Anything on the Old Site
I said $0, but it's possible I could be suckered into something if the price was right and the product worthwhile. I tried using the free version of Beyond, but it just didn't seem like it would be worth paying for after buying the physical products. The subscription model has never appealed to me, even with VTT I use each week. I've considered getting Foundry, but as long as Roll20 is still quite workable at "free," this is a much less appealing option.
I had the same issue, but instead I figured out how to go into my storage and delete everything instead. They don't make this particular option easy to find, but that's to be expected. The size per file is also a bit on the obnoxious side, but I've managed. The only feature that made me consider paying for Roll20 was Dynamic Lighting, but another DM in my group tried using and it was a nightmare.
If you and your players have good internet bandwidth, you might consider Foundry. One time $50 cost. You get best-on-market dynamic lighting, much more easily prepped maps, access to a dizzying number of community mods. If hosting on your own computer, your only storage limits are those of your machine.
I do use a hosting service to host my instance of Foundry, but that mostly because I'm usually running games from an location with not-great bandwidth and my players are in another country. There are other benefits to the hosting service I use, but if I were back working in, and running games from, the United States, I would likely just self-host on my computer. All of my content is fully portable. No lock in.
