Found that issue was caused by saving emoji. Save your locations without emoji, for example https://prnt.sc/8B2u3g30Qtn0
Also, contact your hosting provider and ask they to fix the DB field’s collation type that didn’t support all emoji. Probably it set to utf8_general_ci.
Solution: Change the field collation type to utf8mb4_general_ci to support longer-byte emoji.
