Have the same problem, too (see attachments) 🙃 It's so frustrating to complete the tasks for the rewards - only to not be able to collect the rewards! 😞 I've now been shorted 20 gems so far; after today, it'll be 30. I think there are now more than 8 listed daily activities (with the inclusion of complete a level with a hired plant, for me anyway). So tomorrow, I'll try and complete only 8 activities, then try and collect the gems for "complete 8 daily activities", then carry on with the remaining daily activities, if that makes sense.
