How to prevent my Guidebook from « eating » new things I add to it?

[Julie143]

When I try to add new places to my guidebook, they disappear. I am 100% sure that I save them. Does it have something to do with browser or app version? I had about 20 places in the GB this morning. Now it’s down to about 16. Is there a limit on how many you can add?

Same is happening to me. I updated my guidebook with about 20 additional places and none have appeared yet.
