Since the update to v3.9.1, I have been experiencing problems editing Projects in Firefox and in Safari. The problems are: (i) opening, closing and then opening the same project again leads to a blank screen or very slow opening; (ii) warnings that projects that I have already closed are locked for editing by me; and (iii) unable or very slow logout. These issues do not occur instantly or every time, but after a while of editing Projects they always reoccur. It's all the same even after restarting, deleting cache / cookies or using a private browsing window. Is this a known issue?
Chrome seems fine for me, which makes me think the issue may not be with Xerte potentially not being optimized for M1 MacBooks.
